Find the volume , curved surface area and the total surface area of a cylinder with diameter of base 7 cm and height 40 cm.

Answer»

Volume = πr2h = ((22/7) x (7/2) x (7/2) x 40) = 1540 cm

Curved surface area = 2πrh = (2x(22/7)x(7/2)x40)= 880 cm2

Total surface area = 2πrh + 2πr2 = 2πr (h + r) 

= (2 x (22/7) x (7/2) x (40+3.5)) cm2 

= 957 cm2
