Question

the volume and area of curved surface of a right circular cylinder are 1540m^3 and 440 m square find the radius of the base area and the height of the cylinder

Answer 1

we have
volume of cylinder= 1540m^3
CSA of cylinder= 440 m^2
now,

πr^2h ÷ 2πrh = 1540 ÷ 440
r = 7 m
put the value of r in 2πrh= 440
2×22/7 × 7× h = 440
h = 1 m
