Question

What is the volume of a sphere with a radius of 3 inches?

Answer 1

Answer:

36

Step-by-step explanation:

Answer 2

Answer: The answer is (C) 36π cubic inches.

Step-by-step explanation: We are given to find the volume of a sphere with radius 3 inches.

We know that the volume of a sphere with radius 'r' units is given by

$V=\dfrac{4}{3}\pi r^3.$

Here, we have,

radius, r = 3 inches.

Therefore, the volume of the sphere is given by

$V\\\\=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\pi \times 3^3\\\\=\dfrac{4}{3}\pi \times 27\\\\=36\pi~\textup{cubic inches}.$

Thus, (C) is the correct option.
