Question

The curved surface of area of a cylindrical piller is 264m^2 and its volume is 924 m^3. find the diameter and height of the cylinder.... also your name plese..​

Answer 1

Answer:

6m

Step-by-step explanation:

Curved surface area of cylinder = 264 m²

volume of cylinder = 924 m³

We know that

CSA of cylinder = 2πrh

264 = 2*22/7*r*h

r*h = (264*7)/44

r*h = 1848/44

r*h = 42

h = 42/r ……(1)

Now,

volume of cylinder = πr²h

Substituting the value of h = 42/r in the volume equation, we get

924 = 22/7*r²*42/r

924r = 924*7

r = 7 m

So, Radius is 7 m and the diameter will be 7*2 = 14 m.

And the height of the cylinder =h = 42/r= 42/7 = 6 m
