There are 2 circular bases: A = π r²
A = π (3)²
   = 9 π

There is one lateral face that is a rectangle: A = L x W
In this instance, the length equals the perimeter of the circle: L = 2 π r
A = 2 π (3) x 7
   = 42 π

Surface Area = 2(9 π) + 42 π
                       = 18 π + 42 π
                       = 60 π
                       ≈ 188
