Question

What is the volume of a sphere with a radius of 2.5? answer in terms of pi

options:
-20 5/6π
-25π
-8 1/3π
-15 5/8π

Answer 1

`8 (1)/(3) \pi`

Explanation:

volume of a sphere = 4/3 pi r²

r = 2.5

4/3× pi× 2.5² = 25/3pi

25/3 as a mixed number is 8 and 1/3

therefore rhe answer is 8 and 1/3 pi
