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 cm3 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 |
