प्रश्न
Curved surface area of a right circular cylinder is 4.4 m2. If the radius of the base of the cylinder is 0.7 m, find its height.
`["Assume "pi=22/7]`
उत्तर
Let the height of the circular cylinder be h.
Radius (r) of the base of cylinder = 0.7 m
CSA of cylinder = 4.4 m2
2πrh = 4.4 m2
`(2xx22/7xx0.7xxh)m=4.4m^2`
h = 1 m
Therefore, the height of the cylinder is 1 m.
