Step-by-step explanation: took the test got it right

Answer 2

The required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

What is an area circle?

The area of the circle is given by the pie times square of the radius.

Area of circle = πr^2

Here,
Let the radius of the given circle be r = 5 cm
Area of the circle = πr²

Substitute the value in the above expression,
Area of the circle = π 5²
Area of the circle = 78.5cm²

Thus, the required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

Answers

The measure of arcDF from the figure shown is 30 degrees

Circle geometry

Based on the symmetry of the figure given, we can say that the measure of<DEF is equal to the minor arc DF

Given the following parameters

m∠DEF=30 degrees

Since m∠DEF =  arcDF, hence the measure of arc DF is 30degrees

The measure of arcDF from the figure shown is 30 degrees

○=> Correct option :[tex]\color{plum}\tt\bold{(B)}[/tex]○=> Steps to derive correct option :

We know that :

[tex]\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r[/tex]

So, let the diameter of this circle be x.

Which means :

[tex] =\tt2 \times \pi \times r[/tex]

[tex] =\tt 2 \times x \times \pi = 12\pi[/tex]

[tex] =\tt 2x\pi = 12\pi[/tex]

[tex] =\tt x = \frac{12}{2} [/tex]

[tex] = \tt \: x = 6 \: m[/tex]

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

▪︎Therefore, the correct option is (B)

Answer:

Step-by-step explanation:

You should draw a picture to let everything fall into place:

.................2x.......................

N ----x+7------ O ---10---- P

Then you can easily see that

x+7 + 10 = 2x

17 = 2x - x

so x = 17

NP = 2x = 2*17 = 34

NO = x+7 = 17+7 = 24

OP = 10

Option 3, 18.0

Step-by-step explanation:

To find the Hypotenuse of a right triangle, use the Pythagoras theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

(see image below)

(the longest side of any right △ is always C)

In this equation, we know A is 10 and B is 15, so plug in these numbers and solve for C

[tex]10^{2} +15^{2} =c^{2}[/tex]

[tex]100 + 225 =c^{2}[/tex]

[tex]325 = c^{2}[/tex]

Now that the equation is simplified, we find the square root of 325 to solve for C.

[tex]\sqrt{325 = c^{2}}[/tex]

[tex]18.0 = c[/tex]

The final answer is C = 18.0

Greg has 1/4 as many songs on his computer as mark. Raj has 6 fewer than 60% of the songs that mark has. Mark has 720 songs on his computer.

Answers

Answer:

Greg has 180 songs on his computer

Raj has 426 songs on his computer

Mark has 720 songs on his computer

Step-by-step explanation:

First you find out how much songs Greg has. He has 1/4 as many as mark so 720 x 1/4 = 180. This is because 720 x 1/4 is the same as 720/4. Now we know that Greg has 180 songs on his computer. Next, Raj has 60% of the songs Mark has so 60% of 720 is 432. Because he has 6 fewer than 60%, 432-6=426.

Therefore,

Greg has 180 songs on his computer

Raj has 426 songs on his computer

Mark has 720 songs on his computer

○=> Correct option :

[tex] \color{plum}\bold{(C)} [/tex] Diameter of circle P is the same length as the radius of circle Q.

○=> Steps to derive correct option :

Given :

Diameter of circle P = 26 cm

Radius of circle P :

[tex] =\tt \frac{diameter}{2} [/tex]

[tex] = \tt \frac{26}{2} [/tex]

[tex]\color{plum} = \tt13 \: cm[/tex]

Thus, radius of circle P = 13 cm

Diameter of circle Q = 52 cm

Radius of circle Q :

[tex] = \tt \frac{diameter}{2} [/tex]

[tex] =\tt \frac{52}{2} [/tex]

[tex] \color{plum}= \tt26 \: cm[/tex]

Thus, radius of circle Q = 26 cm

Radius of circle R = 52 cm

Diameter of circle R :

[tex] =\tt radius \times 2[/tex]

[tex] =\tt 52 \times 2[/tex]

[tex]\color{plum} = \tt104 \: cm[/tex]

Thus, the diameter of circle R = 104 cm

☆ Conclusion :

▪︎Diameter of circle P is the same length as the radius of circle Q.

Therefore, the correct option is (C) Diameter of circle P is the same length as the radius of circle Q.
