Question

the curved surface area of the cylinder is 176cm square and base area is 38.5cm square then find the volume of the cylinder​

Answer 1

Answer:

volume  = 308 cm³

Step-by-step explanation:

base area   =  38.5 cm²

  π r²     = 38. 5

22/7 x r²  = 38.5

         r²   = 38.5 x 7/22

               = 12.25

   ∴  r =  3.5 cm

csa of cylinder  =  176 cm²

 2 π r h   = 176

2 x 22/7 x 3.5 x h  = 176

                        h   =( 176 x 7)  / ( 2 x 22 x 3.5)

                           =  8 cm

 Volume of cylinder  = π r² h

                                  =  22/7 x 12.25 x 8

                                 =  308 cm³
