Hello from MrBillDoesMath!
Answer:
2 * (Pi r^2) + (Pi r^2)*h
where r = C/(2 Pi)
Discussion:
Total surface area of cylinder =
area of bottoms + surface area of cylinder =
2 * area of base + (area of base) * h
Generally, C = 2 Pi r, so r = C/(2 Pi) is known as we are given C. . Plugging this in the above equation gives
2 * (Pi r^2) + (Pi r^2)*h
Thank you,
MrB
