Question

a sphere has a diameter of 13 feet. what is the volume of the sphere in cubic feet? (use \\(\pi = 3.14\\)) round the answer to two decimal places if necessary. enter answer cubic feet

Explanation:

Step1: Find the radius

The diameter \( d = 13 \) feet, so the radius \( r=\frac{d}{2}=\frac{13}{2} = 6.5 \) feet.

Step2: Use the volume formula for a sphere

The volume formula for a sphere is \( V=\frac{4}{3}\pi r^{3} \). Substitute \( \pi = 3.14 \) and \( r = 6.5 \) into the formula:
