Question

Find the volume of the figure below.

Answer 1

The dotted lines indicate that this object is a sphere, so we will use the formula for finding the volume of a sphere to solve this problem.

Volume of a sphere: 4/3
`\pi`r³

The figure shows us that the radius of the sphere is 2.8 cm, so we will plug in 2.8 for r in the formula.

4/3
`\pi`2.8³ = 91.95

The volume of the figure is 91.95 cm³.
