Question

What is the surface area of the cylinder? Express the answer in terms of Pi.

A cylinder with a diameter of 8 centimeters and height of 18 centimeters.

Recall the formula S A = 2 pi r squared + 2 pi r h.
152 pi Centimeters squared
176 pi Centimeters squared
304 pi Centimeters squared
792 pi Centimeters squared

Answer 1

Its B) 176 pi cm^2

Explanation:

i got it right! :D

Answer 2

Second option: Surface area = 176*pi cm2

Explanation:

The surface area of a cylinder is given by:

S = 2*pi*r^2 + 2*pi*r*h

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

If we have that the diameter is 8 centimeters, the radius is 8/2 = 4 centimeters. So with r = 4 and h = 18, we have that the surface area is:

S = 2*pi*4^2 + 2*pi*4*18 = 176*pi cm2

So the answer is the second option.
