Question

The curved surface area of a cylinder is 264 m² and its volume is 924 m³. The ratio of its diameter to its height is

(a) 3 : 7

(b) 7 : 3

(c) 6 : 7

(d) 7 : 6

Answer 1

The C.S.A. of cylinder

S = 264 m²

The volume of cylinder

V = 924 m³

From eq. (i) and (ii),

We get

Putting the value in (i)

Hence, the correct answer is choice (b).
