Question

the curved surface area of a cylinder is 1320 cm² and its diameter is 8cm Find its height its height
​

Answer 1

Given :

curved surface area of cylinder = 1320cm²

diameter = 8cm

Radius = diameter/2

= 8/2 cm

= 4 cm

curved surface area of cylinder = 2πrh

2πrh = 1320cm²

2 × 22/7 × 4cm × h = 1320cm²

176h/7 cm = 1320cm²

h = (1320×7)/176 cm

h = 52.6 cm

Hence, the height of the cylinder is 52.6 cm
