Question

What is the volume of a sphere with a radius, r = 0.5?

Use 3.14 for and be sure you round your answer to two decimals.

Answer 1

0.52 cubic units

Explanation:

`V_(sphere) = (4)/(3) \pi {r}^(3) \\ \\ = (4)/(3) * 3.14 * {(0.5)}^(3) \\ \\ = (4)/(3) * 3.14 * 0.125 \\ \\ = (1.57)/(3) \\ \\ = 0.523333333 \\ \\ = 0.52 \: {units}^(3) \\`
