Question

the circumference of the base of a cylinder is 132 cu cm. it's height is 25 cm. what is the volume of the cylinder

Answer 1

hello hope this will help you

Answer 2

Given height h = 25cm.

We know that circumference = 2pir.  ------- (1)

Given circumference of the base of cylinder = 132 cu.cm   ----- (2).

From (1) & (2), the equation can be written as

                 2pir = 132

                 2 * 22/7 * r = 132

                    r = 132 * 7/2 * 22

                      = 924/44

                      = 21cm.


Volume of the cylinder = pir^2h

                                       = 22/7 * 21 * 21 * 25

                                       = 22 * 3 * 21 * 25

                                       = 34650cm^3.

                                       = 34650/1000 litres

                                       = 34.65 litres.


Therefore the volume of the cylinder = 34.65 litres.


Hope this helps!
