Question

Help I’m not great and math

Answer 1

I would say the answer is 60 because base * height

Answer 2

Answer: C. 78 pi

Explanation:
The equation for surface area of a cylinder is; a=2pirh+2pir^2
So a=2 x pi x 3 x 10 + 2 x pi x 3^2
Then follow order of operations, so start with exponent
So a= 2 x pi x 3 x 10 + 2 x pi x 9
Then multiplication, but leave pi since out answer will be in pi

So a = 2 x pi x 30 + 2 x pi x 9
Next multiply 2 x 30 and 2x9
a= pi x 60 + 18
Add
a= 78 pi
