Question

What is the surface are of a cylender when the radius is 6in and the height is 9 in

Answer 1

565.486677646 inches squared

Explanation:

Let's recall the formula for the surface area of a cylinder:

`A=2\pi rh+2\pi r^2`

Where r is the radius and h is the height.

We are given that the radius is 6 inches and the height is 9 inches.

Substitute the values and solve the equation, like so:

`A=2\pi (6)(9)+2\pi (6)^2=\\A=2\pi (54) +2\pi(36)=\\A=108\pi +72\pi =\\A=180\pi`

Thus, in terms of pi, the surface area is equal to
`180\pi`.

180 times pi is equal to approximately 565.486677646 inches squared.
