Question

what is the volume of a cylinder with a height of 3 feet and a radius of 4 feet? use 3.14 for pi. enter your answer in the box. \boxed{} ft³

Explanation:

Step1: Recall the formula for the volume of a cylinder

The formula for the volume \( V \) of a cylinder is \( V=\pi r^{2}h \), where \( r \) is the radius and \( h \) is the height.

Step2: Substitute the given values into the formula

We are given that \( r = 4 \) feet, \( h=3 \) feet, and \( \pi = 3.14 \). Substituting these values into the formula, we get:
\( V=3.14\times(4)^{2}\times3 \)
First, calculate \( (4)^{2}=16 \). Then the expression becomes \( V = 3.14\times16\times3 \).

Step3: Perform the multiplication

First, multiply \( 3.14\times16 = 50.24 \). Then multiply \( 50.24\times3=150.72 \).

Answer:

\( 150.72 \)
