Question

Find the volume of the sphere. express your answer in term of Pie​

Answer 1

`\large\boxed{36\pi}`

Explanation:

The formula of a volume of a sphere:

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

R - radius

We have R = 3 ?. Substitute

`V=(4)/(3)\pi(3^3)=(4)/(3)\pi(27)=(4)\pi(9)=36\pi`

If the radius is 30, then the volume is:

`V=(4)/(3)\pi(30^3)=(4)/(3)\pi(27,000)=(4)\pi(9,000)=36,000\pi`

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.

Therefore the volume:

`V=(4)/(3)\pi(15^3)=(4)/(3)\pi(3,375)=(4)\pi(1,125)=4,500\pi`
