Question

The CSA of a cylinder a 4400 square centimetre and the circumference of its base is 110 CM find the volume of the cylinder

Answer 1

CSA of cylinder = 4400 sq.cm

Circumference of the base = 110 cm

2 Π r  =   110 ==> 2 x (22/7) x r  =  110

r  =  110 x (1/2) x (7/22)  ==> r  =  17.5 cm

diameter  =  2 r

=  2 (17.5) ==> 35 cm 

2 Π r h   =   4400 ==> 110 x  h  =  4400 ==> h  =  4400/110

h  =  40 cm 

Height  =  40 cm

Diameter of the cylinder  =  35 cm

Hence, height and diameter of cylinder are 40 cm and 35 cm respectively.
