cut a rectangle and roll it

Step-by-step explanation:

cut a rectangle

the length will become height and breath will become circumference

Answer 2

Answer:

Step-by-step explanation:

OBJECTIVE

To make a right-circular cylinder of given height and radius of base

Materials Required

A sheet of chart paper

A pair of scissors

A geometry box

A pencil

A roll of Sellotape

Procedure

Step 1: Let the given height of the cylinder be h and radius of the base be r.

Step 2: Calculate the circumference of the base of the required cylinder as 2πr.

Step 3: From the chart paper cut out a rectangle ABCD having lengths 2πr and breadth.
