Question

Which of the following is the surface area of the right cylinder below?

Answer 1

its a i just took it on a p 3 x :)))

Explanation:

Answer 2

Answer: Option A.

Explanation:

You need to use this formula for calculate the surface area of the right cylinder:

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

Where "r" is the radius and "h" is the height.

You can identify in the figure that:

`r=8units\\h=3units`

Knowing this, you can substitute these values into the formula
`SA=2\pi r^2+2\pi rh`, therefore you get that the surface area of this right cylinder is:

`SA=2\pi (8units)^2+2\pi (8units)(3units)`

`SA=176\pi\ units^2`
