Question

Volume of cylinder and hollow cylinder?? ​

Answer 1

Cylindrical Surface is a curved surface generated by parallel duplication of a line. A right hollow circular cylinder is a three-dimensional solid bounded by two parallel cylindrical surfaces and by two parallel circular bases cut out from two parallel planes by these two cylindrical surfaces. The shortest distance from the center of the circular base to the inner cylinder is the inner radius r, and the shortest distance from the center of the circular base to the outer cylinder is the outer radius R. In addition the right circular hollow cylinder apothems (of length h) are perpendicular to the plane of a base circle. pls mark as brainliest
