Question

The curve surface area of a cylinder is 264msq and its volume is 924m cube find the ratio of hight to its diameter

Answer 1

Heay Genius......☺️☺️☺️

Here is your answer......☺️☺️☺️

Solution :-
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 = 7m
So, the diameter of the cylinder is 114m
Now, substituting the value of h = 42/r
h = 42/7
h= 6m
So, the height of the cylinder is 6 m
The ratio of the diameter of the cylinder to its height = 14 :6
= 7:3
Answer.
