Question

curved surface area and circumference at the base of a solid right circular cylinder are 4400 sq.cm and 110 cm respectively. find its diameter​

Answer 1

hey dear

here is your solution .......

Curved surface area 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

Answer 2

Step-by-step explanation:

Solution is

2 pie r h=4400

2(2pie r) =110 because of two circumference of right circular cylinder

Solving two equation u get the answer...
