What is the volume of a sphere with a radius of 3 inches? 12π cubic inches 24π cubic inches 36π cubic inches 48π cubic inches
Anni [7]

Answer:

The answer is

<h2>36π cubic inches</h2>

Step-by-step explanation:

Volume of a sphere is given by

<h3>V =  \frac{4}{3} \pi  {r}^{3}</h3>

where r is the radius

From the question

r = 3 inches

Substitute the value into the above formula and solve for the volume

That's

<h3>V =  \frac{4}{3}(  {3})^{3} \pi \\  =  \frac{4}{3}  \times 27\pi \\  = 4 \times 9\pi</h3>

We have the final answer as

<h3>36π cubic inches</h3>

Hope this helps you
