A rectangular sheet of paper 40cm x 22cm, is rolled to form a hollow cylinder ofheight 40cm. The radius of the cylinder(in cm) is
Question
Solution 1
To find the radius of the cylinder, we need to use the formula for the surface area of a cylinder. The surface area of a cylinder is given by the formula:
Surface Area = 2πrh + 2πr^2
In this case, we know that the height of the cylinder is 40cm. We also know that the rectangular sheet of paper, wh Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
