Question

the perimeter of the base of a right circular cylinder is 44cm and its height is 10cm then it's volume is
​

Answer 1

Answer:

1540 cm^3

Step-by-step explanation:

The perimeter of the base of a right circular cylinder is 44 cm

2πr^2 = 44

r = (44×7)/(22×2) = 7 cm

Volume = πr^2h = 22/7 × 7 × 7 × 10 =1540

Hope it will help you.

Answer 2

Answer:

1540cm3

Step-by-step explanation:

Given : perimeter of a cylinder =2πr=44cm

           and  height(h)=10cm

            radius =7cm { as, 2πr=44=> r=(44*7)/(22*2)}

Lateral surface area of a cylinder =2πrh

          = circumference of the base × height of the cylinder

          =44×10=440cm

∴Lateral surface area of a cylinder is 440sq.cm.

The volume of the circular cylinder=$\pi$ *r*r*h

=22*7*7*10/7

=1540cm3

therefore, the volume of the circular cylinder is 1540cm3.
