Question

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

Answer 1

Answer:

H. 3 units

Step-by-step explanation:

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

$V=\frac{4}{3} \pi r^{3}$

Plugging the given number into V, we calculate that:

$113 = \frac{4}{3}\pi r^{3}\\84.75 = \pi r^{3}$

If π=3.14, the radius is:

r ≈ 3 units.
