Question

The volume of cylinder is 3960cm^2.C.S.A is 1320. Find r and h

Answer 1

Answer: Radius(r) = 6,   Height(h) = 110/π

Step-by-step explanation:

Volume of cylinder = πr^{2}h

3960cm^3 = πr^{2}h

C.s.a = 1320cm^2

2πrh = 1320cm^3

3960/1320=πr^{2}h/2πrh

3=r/2

R=6

2πrh = 1320

2 X 6 X h X π = 1320

h = 110/π
