Question

Find the total surface area of a cylinder with a height of 7 cm and radius of 3 cm. Leave your answer in terms of π.

140π cm2
91π cm2
60π cm2
51π cm2

Answer 1

\[Surface~area~of~cylinder:~~ 2\pi r^2 + 2\pi r(h)\]

Answer 2

So you have \[2\pi(9)+2\pi(3)(7) = 18\pi + 42\pi\] and then you can get your answer

Answer 3

60π cm2

Answer 4

yes
