Question

the radius and height of a cylinder are in the ratio of 11:7.if the covered surface of the cylinder is 121 square cm,find it height and radius.provide pic with steps and caluculation and dont spam

Answer 1

Step-by-step explanation:

let the ratio of radius and height of cylinder be 11a and 7a

curved surface area=2πrh

2×22/7×11a×7a=121

484a²=121

a²=1/4

a=1/2

radius=11/2cm

height=7/2cm
