Question

The total surface area of a cylinder is 6512 cm^2 and the circumference of its bases is 88 cm. Find:

Answer 1

circumference = 88cm
2 pie r = 88
2×22/7×r = 88
r = 88×7/22×1/2
r = 14cm
Total surface area = 6512
2pie r (h+r) = 6512
2×22/7×14(h+14) = 6512
88(h+14) = 6512
h+14 = 6512/88
h+14 = 74
h = 74-14
height = 60cm
