|
Answer» Given: Circumference of the base of cylinder = 132 cm and height (h) = 25 cm To find: Volume of the cylinder i. Circumference of base of cylinder = 2πr ∴ 132 = 2 x (22/7) x r ∴ (132 x 7/2 x 22) = r (6 x 7)/2 = r ∴ 3 x 7 = r ∴ r = 21 cm ii. Volume of the cylinder = πr2h = (22/7) x 21 x 21 x 25 = 22 x 3 x 21 x 25 = 34650 cc ∴ The volume of the cylinder is 34650 cc. |
