Question

The curved surface area of right circular cylinder is 6.6m square. If the radius of the base of a cylinder is 0.64m, find its height?

Answer 1

Answer:

Step-by-step explanation:

C.S.A = 6.6m²

Converting in cm = 6.6 x 10000

= 66000cm²

base = 0.64m = 64 cm

h = ?

C.S.A = 2πRH

⇒ 2 x 22/7 x 64 x h = 66000

h = 66000 x 7 / 44 x 64

= 164.06cm

Answer 2

Using The Formula
Area = 2πrh = 6.6 m^2
And Radius = 0.64 m
So Height = 6.6×7÷44×0.64
So Height = 1.640 m (approximate)
