What is the volume of the cylinder with a radius of 8 and height of 4<br><br>

mr Goodwill [35]

Answer:

Hey there!

The formula for cylinder volume is $r^2h\pi$ , where r is the radius, h is the height, and $\pi$ is a constant, roughly equal to 3.14.

Substituting all of these values into the equation:

$8^2(4)(3.14)$

$804.84\\$

Thus, the volume for the cylinder is 804.84 units cubed.

Hope this helps :)
