Question

Calculate the VOLUME of the sphere that has a circumference of 140pi. Round to the nearest tenth. (Don’t mind the -1)

Answer 1

Rounded to the nearest tenth, the volume is 1,437,773.5 cubic units.

Explanation:

First, we need to use the formula for the circumference of a sphere to find the radius:

C = 2πr

140π = 2πr

r = 70

Now we can use the formula for the volume of a sphere:

V = (4/3)πr^3

V = (4/3)π(70)^3

V ≈ 1,437,773.5
