Question

the curved surface area of a right circular cylinderof height 14 cm is 88 CM squarefind the diameter of the base of the cylinder

Answer 1

Height of cylinder = 14 cm

CSA of cylinder = 88 cm^2

=> 2 pi r h = 88

=> 2 × 22 × r × 14 / 7 = 88

=> 44r × 2 = 88

=> r = 1

Radius = 1 cm

Diameter of Base of cylinder = 2 cm

Answer 2

Given : CSA of cylinder = 88cm square.
Height = 14 cm
we know that csa = 2pirh
so 2 × 22/7 × r × h = 88
88r = 88
r = 1
d = 2r
hence diameter = 2cm
