Question

A bowling ball has a diameter of 8in. Find it’s volume. Round answer to two decimal places

Answer 1

V = 268.08 in^3

Explanation:

The formula for the volume of a sphere of radius r is V = (4/3)(pi)(r^3).

Here we are told that the diameter is 8 in. Therefore, the radius is 4 in.

Calculating the volume, we get:

V = (4/3)(3.14159)(4 in)^3, or

V = 268.08 in^3

Answer 2

V = 27.16inch^3

Explanation:

Find the radius = 8/2 = 4

V=4/3 π r3

V=4/3 π * 4 x 4 x 4

V=4/3 π * 64

V = 4/3 π = 0.42441318157 = π +1/3 Take this and multiply to 64

0.42441318157 x 64 = 27.1624436205 = 27.162444

V = 27.16inch^3
