Question

The radius of a sphere is 3 cm. What is the sphere's volume? Round to the nearest tenth.

Answer 1

it is c

because if u added it up u can see the thing to dd it up

Answer 2

`\large\boxed{V=113\ cm^3}`

Explanation:

The formula of a volume of a sphere:

`V=(4)/(3)\pi R^3`

R - radius

We have R = 3cm. Substitute:

`V=(4)/(3)\pi(3^3)=(4)/(3\!\!\!\!\diagup_1)\pi(27\!\!\!\!\!\diagup^9)=(4\pi)(9)=36\pi\ cm^3\\\\\pi\approx3.14\\\\V\approx(36)(3.14)=113.04\ cm^3\approx113\ cm^3`
