Question

A sphere has a volume of approximately 113 cubic units. Which of the following best represents the radius of the sphere?

F. 4 units
G. 2 units
H. 3 units
J. 5 units

Answer 1

H. 3 units

Explanation:

In order to answer this question, we have to apply the formula for the sphere volume. The formula is:

`V=(4)/(3) \pi r^(3)`

Plugging the given number into V, we calculate that:

`113 = (4)/(3)\pi r^(3)\\84.75 = \pi r^(3)   \\`

If π=3.14, the radius is:

r ≈ 3 units.
