Question

the curved surface area of cylinder kal pillar is 264 metre and its value is 924 metre cube find the diameter and the height of the pillar ​

Answer 1

Answer:

Diameter= 14 m and height= 6 m

Step-by-step explanation:

Let r and h are the radius and height of the pillar

Then CSA= 2πrh=264 m²..................(1)

and Volume V=πr²h=924....................(2)

Dviidng (2) by(1)

πr²h/2πrh =924/264

r/2=3.5, r=7 m

Thuis diameter =14 m

From(1)

2*(22/7)*7*h=264

h=(264*7)/(2*22*7)=6 m
