Question

the circumference of the base of a cylinder is 44cm and hight is 7cm find the volume and lateral surface area
​

Answer 1

Answer:

Step-by-step explanation:

Circumference of the base = 2πr = 2*22/7*r = 44

r = 44 X 7/44

 = 7 cm

Radius = r = 7 cm

Height = h = 7 cm

Volume = πr²h

            = 22/7 X 7 X 7 X 7

            = 1078 cm³

L.S.A of cylinder = 2πrh

                           =2πr X h

                           = 44 X 7

                           = 308 cm²

∴L.S.A of the cylinder is 308 cm²

∴ volume is 1078 cm³
