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, The Correct Answer would be Option "B".


Hope this Helps! Have A WONDERFUL Day! :)

Surface area = 2πr(h + r)
= 2π × 27(37+27)
= 2 × 27 × 64 × π
= 3456π
