Question

Can someone please me on that one ? Thanks an advance ? Don't forget to show your work :)

Answer 1

Hello Gary!

Surface area of a cylinder = 2 x Pi x r^2 + 2 x Pi x r x h

R = 27 cm
H = 37 cm

Take away the Pi seeing as you want to keep it in terms of Pi

2 x 27^2 + 2 x 27 x 37 = 3456 Pi cm^2

Therefore, Your Answer is Option "B".


Hope this Helps! Have A Wonderful Day! :)

Answer 2

One cylinder has two bases and one side, and the side is a rectangle.

So S = 2*base + side

S = 2* (pi*27^2) + (2*pi*27*37) = 3456pi
