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

Snowcat [4.5K]

Answer: Option A.

Step-by-step 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:

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

$SA=176\pi\ units^2$
