What is the volume of a cylinder with a height of 2 feet and a radius of 6 feet? Use 3.14 for pi. Enter your answer in the box.

erastovalidia [21]

Answer:

$V=226.08\ ft^3$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

where

r is the radius of the base of the cylinder

h is the height of the cylinder

we have

$r=6\ ft\\h=2\ ft\\\pi=3.14$

substitute the given values in the formula

$V=(3.14)(6)^{2}(2)\\ V=226.08\ ft^3$
