Answer 1

@iGreen.

Answer 2

Formula:

\(SA = \pi r^2 + \pi r l\)

Where 'r' is the radius, and 'l' is the slant height.

Plug in what we know:

\(SA = (3.14) (4)^2 + (3.14) (4) (7)\)

Can you simplify that?

Answer 3

Yes, hold on so I can solve it.

Answer 4

Answer 5

Is that right @iGreen.

Answer 6

Yep, I got the same thing, so your answer is 138.
