What Is The Surface Area Of This Composite Solid?

Answers

Answer 1

The surface area of the given composite solid is calculated as: 200.24 square units.

How to Find the Surface Area of the Composite Solid?

Surface area of the composite solid = surface area of rectangular prism + surface area of cylinder - 2(area of the base of the cylinder)

Surface area of rectangular prism = length * width * height = 10 * 3 * 5

= 150 square units.

Surface area of cylinder = 2πr(h + r)

height (h) = 4

Radius (r) = 2

Plug in the values:

Surface area of cylinder = 2 * 3.14 * 2(4 + 2) = 75.36 square units

Area of the base of the cylinder = πr² = 3.14 * 2²

= 12.56 square units

Thus, we have:

Surface area of the composite solid = 150 + 75.36 - 2(12.56) = 200.24 square units.

Answers

The sculpture's base length = 9 cm and the height of sculpture is found as 6 cm.

Explain about the pyramid:

The base and apex are joined to form a pyramid. To identify them from the base, the triangular sides are also also referred to as lateral faces. In a pyramid, the apex, which creates the triangle face, is connected to each base edge.

volume of a pyramid = V=1/3 a²h Given volume V = 162 cm³Let 'x' be the side length.Then , (x - 3)  be the height of sculpture.

Put the values and find the length.

162 = 1/3 (x)² (x-3)

162 * (3) =  (x)² (x-3)

486 = x²(x-3)

486 = x³ - 3x²

x³ - 3x² - 486 = 0

Using a graphing tool or by hand answer the questions below.
a) What was the population of the town in 2005?
I
b) In what year will the population exceed 100 000?

Answers

Answer: Therefore, the population will exceed 100,000 in the year 2005 + 10.73 ≈ 2016.

Step-by-step explanation:   a) The population of the town in 2005 is given by the formula, where t = 0 since 2005 is the starting year:

P = 50,000(1.15)^0 = 50,000

Therefore, the population of the town in 2005 was 50,000.

b) We need to find the value of t when the population P exceeds 100,000:

100,000 = 50,000(1.15)^t

Divide both sides by 50,000:

2 = 1.15^t

Take the natural logarithm of both sides:

ln 2 = ln (1.15^t)

Apply the power rule of logarithms:

ln 2 = t ln 1.15

Divide both sides by ln 1.15:

t = ln 2 / ln 1.15

Using a calculator, we get:

t ≈ 10.73

Hence, the darkened sector covers an area of roughly [tex]10.55 km^2[/tex] as circle's radius is 7 km, and the shaded sector's central angle is 154 degrees .

what is radius ?

The radii of a circle in geometry is the separation between any two points on the circle's circumference. It is frequently used to describe how far apart two points are. One of a circle's most crucial characteristics is its radius, which is taken into account when calculating a circle's circumference, area, and diameter. The distance around a circle that passes through its centre, or its diameter, is equal to half of its radius. Other shapes like spheres, cylindrical, and cones can also be described using the radius. The radius here means the distance from the shape's centre to any point on its perimeter.

given

The following formula must be used to determine a sector's area:

A = (θ/360)[tex]\pi r^2[/tex]

where r is the circle's radius, is pi, or roughly 3.14, and is the sector's centre angle, expressed in degrees.

The circle's radius is 7 km, and the shaded sector's central angle is 154 degrees, according to the provided figure. When these values are added to the formula, we obtain:

[tex]A = (154/360)\pi (7)^2[/tex]

Sin A Cos A, and Tan A can be found respectively as follows:

1. 41.81°.

2. 44.19 degrees

2. 60 degrees

How to find the angles

The angles can be found by following the rules for right-angled triangles. This can be achieved in the following ways:

1. sin A= opposite/hypotenuse

sin A = 6/9

Now we take the sine inverse:

sin^-1(6/9)

=  41.81°.

2. Cos 45° = Adjacent/hypotenuse

= cos 45° = x/4

x = cos 45° × 4

= 0.707 × 4

= 2.82

cos A = b2 + c2 – a2 ÷ 2bc

2.8² + 4² - a² ÷ 2×2.8×4

23.84 - 2.8² ÷ 22.4

23.84 - 7.84 ÷ 22.4

Cos A = 0.7142

= 44.19 degrees

3. tan A = Opposite/Adjacent

tan 60°  = 4/x

x = 4/tan 60°

x = 4/1.732

= 2.309

Tan A = 4/2.309

= 1.732

After 8 years, Fabian earned $1430 in simple interest from a CD into which he
initially deposited $5500. What was the annual interest rate of the CD?
A. 0.48%
B. 4.8%
C. 0.325%
D. 3.25%

Answers

Answer:

D. 3.25%

Step-by-step explanation:

The formula for simple interest is:

I = Prt

where I is the interest earned, P is the principal, r is the annual interest rate, and t is the time in years.

We are given that:

I = $1430

P = $5500

t = 8 years

Substituting the values:

$1430 = $5500 * r * 8

Simplifying, we get:

r = $1430 / ($5500 * 8)

r = 0.0325 or 3.25%

Therefore, the annual interest rate of the CD is 3.25%.

A man drove 14 miles directly east from his home, made a left turn at an intersection, and then traveled 7 miles north to his place of work. If a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?

Answers

We can use the Pythagorean theorem to find the distance between the man's home and his place of work.

The distance traveled east and the distance traveled north form the two legs of a right triangle, and the distance we want to find is the hypotenuse.

Using the Pythagorean theorem, we have:

distance^2 = (14 miles)^2 + (7 miles)^2
distance^2 = 196 + 49
distance^2 = 245
distance = sqrt(245)
distance = 15.62 miles (rounded to the nearest tenth)

Therefore, the distance between the man's home and his place of work, if a road was made directly between them, would be approximately 15.6 miles.

A matrix is a rectangular array of numbers arranged in rows and columns. In linear algebra, matrices can be used to represent linear transformations and solve systems of linear equations.

In the given matrix, we need to perform a row operation to get a 1 in row 1, column 1. Row operations are operations performed on the rows of a matrix to transform it into another matrix that is equivalent in terms of solutions to a system of linear equations.

The three types of row operations are:

Swapping two rows.

Multiplying a row by a non-zero constant.

Adding a multiple of one row to another row.

To perform this row operation, we first multiply row 1 by 12 to get a multiple of 12 in the first column of row 1:

[tex]\begin{bmatrix}84 &-48 &96 \\-12& 7& -13\end{bmatrix}[/tex]

Next, we add row 1 to row 2 multiplied by 2 to get a 0 in column 1 of row 2:

[tex]\begin{bmatrix}84 &-48 &96 \\0& 11& 79\end{bmatrix}[/tex]

Finally, we can divide row 1 by 84 to get a 1 in row 1, column 1:

[tex]\begin{bmatrix}1 &-\frac{4}{7} &\frac{4}{7} \\0& 11& 79\end{bmatrix}[/tex]
