1.	Surface. 11. The curved surface area of a cylindrical pillar is 264 m² and its volume is 924 mº.Find the diameter and the height of the pillar.
Answer» diameter=14mheight=6mStep-by-step explanation:Given that:Curved surface area of cylinder = 264 m²volume of cylinder = 924 m³We know thatCSA of cylinder = 2πrh264 = 222/7rhrh = (2647)/44rh = 1848/44rh = 42h = 42/r ……(1)Now,volume of cylinder = πr²hSubstituting the VALUE of h = 42/r in the volume equation, we get924 = 22/7r²42/r924r = 9247r = 7 mSo, Radius is 7 m and the diameter will be 7*2 = 14 m.And the HEIGHT of the cylinder =h = 42/r= 42/7 = 6 mhope it HELPS...
