Question

1. Consider a sphere with a radius with an 18 inches.
Part A: Determine the surface area of the sphere.
A=44712
A 4x1TX 19 X 18
A=4071.5
Part B: Determine the volume of the sphere.​

Answer 1

Answer:

Part A: 4071.5

Part B: 24429.02

Explanation:

Part A: Area of a sphere = 4 x pi x r^2

Radius is 18 inches. 4 x pi x (18)^2 = 1296 x pi = 4071.5...

Part B: Volume of a sphere = $\frac{4}{3}$ x pi x r^3

Radius is 18 inches. $\frac{4}{3}$ x pi x (18)^3 = 7776 x pi = 24429.02
