Question

the radius and height of cylinder are in ratio 2:3 and volume is 1617cm3 find its height

Answer 1

let the radius and height be

2x and 3x

Volume=Pi×r^2×h
1617=22/7×4x^2×3x
1617×7/22=12x^3
1617×7/22×12=x^3
42.875=x^3
cube root 42.875=x
3.5=x

radius=7cm
Height=10.5cm

Answer 2

Answer:

• Radius = 7 cm

• Height = 10.5 cm
