Question

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

​

Answer 1

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 :)

Answer 2

Answer:

804.25 $units^{3}$

Step-by-step explanation:

The formula of the volume of a cylinder is $V=\pi r^{2} h$ where r represents the radius and h represents the height. To find a more exact answer, I usually use pi in my calculator rather than 3.14, unless asked to do so.

$V=\pi (8)^{2} (4)$

$V=\pi (64)(4)$

$V=\pi (256)$

$V=804.25$
