Answer» Answer: It is given that VOLUME of a cylinder = 1650cm. pir^2h = 1650 ---- (1) It is given that CURVED surface area of cylinder = 660cm. 2pirh = 660cm. ----- (2) On solving (1) and (2) we get R/2 = 1650/660 r = 1650/330 r = 5cm. Substitute r = 5 in (2), we get 2pirh = 660 2 * 22/7 * 5 * h = 660 2 * 22 * 5 * h = 660 * 7 220 * h = 4620 h = 4620/220 h = 21cm Therefore the radius of the cylinder = 5cm. the height of the cylinder = 21cm.
