Step-by-step explanation:
The trick is to find the radius. The surface area does that.
A =4* pi * r^2
20096 = 4 * 3.14 * r^2
20096 / 4 = 3.14 * r^2
5024 = 3.14 * r^2
5024 / 3.14 = r^2
r^2 = 1600
√r^2 = √1600
r = 40
Now all you do is use r to find the Volume
V = (4/3) * 3.14 r^3
V = (4/3) * 3.14 * 40^3
V = 1.333 * 3.14 * 64000
V = 26796.67
