___ cm is the height of a cylinder whose radius is 14 cm and the total surface area is 2640 sq.cm
Given, the radius (r) is 14cm. Let h be the height of the cylinder. Total surface area of cylinder = 2 π r2 + 2 π r h
2640 = 2 x 227 x (14)2 + 2 x 227 x(14) h .
Hence, h = 16 cm.
The total surface area of a cylinder whose radius is 4cm and height is 10cm is _____ cm2
