Question

the diameter of a cylindrical water tank is 13 ft, and its height is 15 ft. what is the volume of the tank? use the value 3.14 for π, and round your answer to the nearest whole number. be sure to include the correct unit in your answer. incorrect the value in your answer is incorrect.

Explanation:

Step1: Calculate the radius

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

Step2: Use the volume formula for a cylinder

The volume formula for a cylinder is \(V=\pi r^{2}h\). Substitute \(\pi = 3.14\), \(r = 6.5\) ft, and \(h=15\) ft into the formula.
