What is the volume of a cylinder with a height of 3 feet and a radius of 4 feet use 3.14 for pi
Vlad1618 [11]

Answer:

\large\boxed{V\approx150.72\ ft^3}

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

We have the height H = 3ft and the radius r = 4ft. Substitute:

V=\pi(4^2)(3)=\pi(16)(3)=48\pi\ ft^3

\pi\approx3.14

V\approx48(3.14)=150.72\ ft^3
