Question

cylinder base perimeter is 44cm and height is 8 cm find the volume of cylinder​

Answer 1

Answer:

1232 cm3

Step-by-step explanation:

perimeter of circle = 2 pi r = 44 cm2

                             r  = 2 22/7 r= 44

                              r =44*7/44

                              r = 7

volume of cylinder = pi r2 h

                               = 22/7 * 7*7*8                        

                               = 22*7*8

                               = 1232 cm3                          

Answer 2

Answer:

1232 cm^3

Step-by-step explanation:

Let the radius be 'r' cm.

Now,

Perimeter of cylinder's base =44cm

or,2×pie×r = 44cm

or,2×22/7×r = 44cm

or, 'r' = 44×7/2×22cm

or, 'r' = 7 cm

Therefore, 'radius' = 7cm.

Also,

Volume of the cylinder = Pie×r^2×h

=22/7×7^2×8 cm^3

=1232 cm^3.
