Question

A crystal ball has a radius of 4 inches. What is the approximate volume of the crystal ball? Use 3.14 for Pi. Round to the nearest tenth. Recall the formula Sphere Volume = four-thirds pi r cubed. 50.2 cubic inches 67.0 cubic inches 267.9 cubic inches 2,143.6 cubic inches

Answer 1

c

Explanation:

Answer 2

The volume of the crystal ball is 267.9 inches³

Explanation:

To find the approximate volume of the crystal ball with a radius of 4 inches , we will follow the steps below;

first write the formula for calculating the volume of a sphere

v=
`(4)/(3)` πr³

where r is the radius of the crystal ball and v is the volume of the crystal ball

from the question given, radius = 4 inches and π = 3.14

we can now proceed to insert the values into the formula

v=
`(4)/(3)` πr³

=
`(4)/(3)` × 3.14 ×4³

=
`(4)/(3)` × 3.14 ×64

=803.84/3

≈267.9

v≈ 267.9 inches³

The volume of the crystal ball is 267.9 inches³
