Question

Find the surface of each figure. Round your answer to the nearest tenth.​

Answer 1

Hey there!

I believe your answer would be 282.7.

The formula should be 2πrh+2πr^2. So, 2·π·3·12+2·π·3^2.

Round the answer to the nearest tenth, and you will get 282.7!

Hope this helps!

Have a great day!

Answer 2

282.7 ft^2

Explanation:

Surface area=2*pi*r(r+h)

2*pi*3*(15)=282.7 ft^2
