Answer: The radius is 3 units

Explanation:

V = 4/3 π r3

36 π = 4/3 π r3

36 π / (4/3 π) = r3

27 = r3

3√27 = r

r = 3

The radius is 3 units.

Answer:

The radius is 2.05 units

Explanation:

The volume of a sphere is found using the formula V = 4/3 πr³. Substitute V = 36 and solve for r.

V = 4/3 πr³

36 = 4/3 πr³

36 * 3/4 = πr³

108/4 = πr³

27/ π = r³

8.6 = r³

2.05 = r
