Question

What is the surface area of the cylinder?

Answer 1

594π ft2
378π ft2
540π ft2
216π ft2

Answer 2

The total formula for both surface areas of the circles and of the cylinder would be 2 x pi x r x r plus 2 x pi x r x h
= 2 x pi x 9 x 9 (equals 509 to the nearest whole number) added to 2 x pi x 9 x 12 = 679 to the nearest whole number. adding both would give you 1188 ft squared to the nearest whole number(:

Answer 3

I dont have that number on my answer choices though..

Answer 4

I need help with this one too..

What is the surface area of the cone?

336π cm2
136π cm2
200π cm2
264π cm2

Answer 5

OOH I GOT IT

Answer 6

They're not asking for the total surface area; they're asking for the surface area of the cylinder. In that case, it's only 2 x pi x 9 x 12 which would be 216ft 2
