Given that = 3.14, calculate the circumference of the circle with radius 10cm.
Solve for the area of this triangle, explanation would be greatly appreciated!
9514 1404 393
Answer:
13√731 ≈ 351.48 cm²
Step-by-step explanation:
When given three sides of a triangle, there are a number of ways that the area may be calculated. Perhaps the most straightforward is the use of Heron's formula.
Where s is the semi-perimeter, the area is given by ...
A = √(s(s -a)(s -b)(s -c)) . . . . . . . . s = (a+b+c)/2
Here, the value of s is ...
s = (30 +30 +26)/2 = 43
A = √(43(13)(13)(17)) = 13√(43·17)
A = 13√731 ≈ 351.48 . . . . . square centimeters
_____
Additional comments
This triangle is isosceles, so the altitude can be found from the Pythagorean theorem:
h² +13² = 30²
h = √(900 -169) = √731
Then the area is ...
A = (1/2)bh = (1/2)(26 cm)(√731 cm) = 13√731 cm²
__
You can also find one of the angles using the Law of Cosines, then find the area from ...
Area = (1/2)a·b·sin(C) . . . . . . for any two sides a, b, and enclosed angle C
__
Ultimately, all of these methods are equivalent to Heron's formula.

An industrial factory makes 4 3/5 yards of
chain every minute. The cost of each yard of
chain is $6.59. What is the total cost for all
chain produced in 10 minutes?
The total cost for all chains produced in 10 minutes will be $303.14.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
An industrial factory makes 4 ³/₅ yards of chain every minute. Then the rate is given as,
Rate = 4 ³/₅
Rate = 4 + 3/5
Rate = 4 + 0.60
Rate = 4.60 yards per minute
The cost of each yard is $6.59. Then the cost per minute is given as,
⇒ $6.59 x 4.60
⇒ $30.314 per minute
Then the total cost for all chains produced in 10 minutes will be given as,
⇒ $30.314 x 10
⇒ $303.14

The length of a rectangle is
8 inches longer than the
width. If the ratio of the
length to perimeter is 5:16,
what is the area of the
rectangle?
Answer:
Step-by-step explanation:
The area of the rectangle is 240 square inches if the length of a rectangle is 8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is given that:
The length of a rectangle is 8 inches longer than the width. If the ratio of the length to the perimeter is 5:16
As we know, the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
Let l and w be the length and width of the rectangle:
l = 8 + w
w = l - 8
l/P = 5/16 (the length to the perimeter is 5:16)
P is the perimeter of the rectangle.
P = 2(l + w)
l/[2(l + w)] = 5/16
16l = 10(l + w)
8l = 5(l + l - 8)
8l = 10l - 40
2l = 40
l =20 inches
w = 20 - 8 = 12 inches
Area = 20x12 = 240 square inches
Thus, the area of the rectangle is 240 square inches if the length of a rectangle is 8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.

In a batch of eggs, 3% were broken. There were 18 broken eggs
How many eggs were there in the batch?
Answer: 600 eggs
Step-by-step explanation:
Let total number of eggs be x.So, 3% of x were broken and there were 18 broken eggs. We can write this as: 0.03*x =18x=18/0.03x= 600 eggs (answer).
Total number of eggs in the bags are 600.
What is Percentage?Percentage is a number or ratio that can be "expressed as a fraction of 100".
According to the question,
Percentage of broken eggs = 3%
Number of broken eggs = 3/100 = 0.03
To calculate the total number eggs,
[tex]\frac{3}{100}[/tex] (x) = 18
x = 1800/3
x = 600.
Hence, the total number of eggs in bags are 600.

A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that had 3840 seats. The students left 2496 seats vacant. What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answer:
The answer is 35%
Step-by-step explanation:
To work out percentage.
(No. Of students / Total Available Seats) * 100
1,344 ÷ 3840 = 0.35
0.35 * 100 = 35%
So, the answer is 35%
Hope this helps! :)
The percentage of the seats in the theater were filled by the 6th graders on the trip will be 35%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Total seats in theater = 3840
And, The students left 2496 seats vacant.
Now,
Find the percentage of the seats in the theater were filled by the 6th graders on the trip as;
Since, Total seats in theater = 3840
And, The students left 2496 seats vacant.
So, Number of students in 6th grade = 3840 - 2496
= 1344
Hence, The percentage of the seats in the theater were filled by the 6th graders on the trip;
= 1,344 / 3,840 x 100
= 35%
Thus, The percentage of the seats in the theater were filled by the 6th graders on the trip will be 35%.
