Solution:
Volume of cylinder = 1650cm2πr2h = 1650
___(i)Surface area of the cylinder = 2πrh
660 = 2πrh ___(ii)
Form eqn. (i) and eqn. (ii)
r = 5cmPut in the equation. (2)
660 = 2π × 5 × h
h = 21cm
MathematicsThe volume and curved surface area of the cylinder are 1650cm3 and 660cm2 respectively. Find the radius and height of the cylinder.
