Question

What is the radius of the sphere?

Answer 1

Answer:
radius of sphere = 9 ft

Explanation:
Volume of the sphere can be calculated using the following rule:
V = (4/3) * pi * (r)³
where:
V is the volume = 972 pi
r is the radius we want to find

Substitute with the givens in the equation to get the radius as follows:
972 pi = (4/3)*pi*(r)³
972 = (4/3) * (r)³
(r)³ = 972 * (3/4)
(r)³ = 729
r = ∛729
r = 9 ft

Hope this helps :)

Answer 2

The volume formula for a sphere is 4/3 • pi • r^3. set this equal to 972pi and solve for r. you get r^3 = 1296, so r= 10.9
