Question

if the curved surface area of cylinder is 264sq mt nd volume is 924cubic metre,then the ratio of radius/ height will be what???​

Answer 1

Answer:

Step-by-step explanation:

Curved Surface Area of the cylinder = 2πrh

264 = 2*22/7*r*h

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

rh = 42

h = 42/r ...........(1)

Volume of the cylinder = πr²h

924 = 22/7*r²*42/r

r = (924*7)/(22*42)

r = 7 m 

So, the diameter of the cylinder is 14 m

Now, substituting the value of h = 42/r

h = 42/7

h = 6 m

So, the height of the cylinder is 6 m

The ratio of the diameter of the cylinder to its height = 14 :6

= 7 :3
