Answer 1

Answer:

B. 36

Step-by-step explanation:

Answer 2

Keywords:

Volume, sphere, radio

For this case we must find the volume of a sphere, which has a radius of 3 inches. To do this, we must bear in mind that, by definition, the volume of a sphere is given by:

$V = \frac {4} {3} * \pi * r ^ 3$, where "r" represents the radius of the sphere.

So, substituting, we have:

$V = \frac {4} {3} * \pi * 3 ^ 3\\V = \frac {4} {3} * \pi * 27\\V = 36\pi$

Thus, the volume of the sphere is $36\pi$ cubic inches

Answer:

The volume of the sphere is $36\pi$cubic inches
