Question

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

​

Answer 1

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

804.25
`units^(3)`

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`
