Question

circumference of a cylinder is 220cm and height is 63cm then CSA is​

Answer 1

Answer:

Given,

Circumference of a cyclinder = 220 cm

Height = 63 cm

CSA of a cylinder = 2πrh

                             = 2 x $\frac{22}{7}$ x 220 x 63

                             =2 x 22 x 220 x 9

                             = 87120 cm²

∴ CSA of the cylinder = 87120 cm²
