Question

Find the volume of the sphere Formula: V= 4/3 * 3.14 * r^3

Answer 1

First, to solve this problem, we need to use the formula for the circumference of the middle section of the sphere to find its radius:

C = 2pi * R

Given that C = 20pi, we get:

20pi = 2pi * R

Divide both sides by a factor of 2pi

R = 10 cm

Now, using the
