Question

find its height. Find the height of a cylinder whose diameter is 42 cm and the area of its curved surface is 11,880 sq. cm.​

Answer 1

Answer:

height = 90cm

Step-by-step explanation:

Let the height of the cylinder be x.

Curved surface area of a cylinder = 2πrh

radius=42cm/2=21cm

11880=2×22/7×21×x

11880/2×7/22×1/21=x

90cm=x

Hence, height = 90cm
