The area of each circle

Katyanochek1 [597]

Answer:

8. $25\pi$ $in^2$

11. $9\pi$ $m^2$

Step-by-step explanation:

Area = $\pi r^2$

r = d/2

$\pi$ = 3.14

r = 10/2

r = 5 in

Area = $\pi 5^2$

Area = $25\pi$ $in^2$

10.

r = 6/2

r = 3 m

Area = $\pi 3^2$

Area = $9\pi$ $m^2$

Hope it helps! (:

The volume of a sphere can be described by the following formula, where V = volume and r = radius of the sphere.

Anika [276]

Option C: $r = \sqrt[3]{\frac{3V}{4\pi} }$ is the right answer

Step-by-step explanation:

Given formula for volume of a sphere is:

$V = \frac{4}{3}\pi r^3$

We have to make r the subject of the formula

Multiplying equation by 3/4

$\frac{3}{4}V = \frac{4}{3} * \frac{3}{4} \pi r^3\\\frac{3}{4}V = \pi r^3$

Dividing both sides by pi

$\frac{3}{4\pi}V =\frac{ \pi r^3}{\pi}\\\frac{3V}{4\pi} = r^3$

Taking cube root on both sides

$\sqrt[3]{\frac{3V}{4\pi} } = \sqrt[3]{r^3} \\ r = \sqrt[3]{\frac{3V}{4\pi} }$

Hence,

Option C: $r = \sqrt[3]{\frac{3V}{4\pi} }$ is the right answer
