Question

a rectangular sheet of paper of length 35 cm and breadth 28 cm is folded into ways to form a cylinder find the difference in the volumes of cylinders formed. pi is equal to 22 by 7

Answer 1

Answer:

Step-by-step explanation:

Given rectangular sheet of paper is rolled along its breadth length = 28 cm breadth = 22 cm Hence height of cylinder, h = 28 Circumference of the base of cylinder = 2πr = 22 cm 2 × (22/7) × r = 22 Therefore, r = 7/2 = 3.5 cm Volume of cylinder = πr2h = (22/7) × (3.5)2 × 28 = 1078 cu cm Thus the volume of the cylinder is 1078 cu cm.
