Question

the volume of right circular cylinder is 1100cm3 and radius of its base is 5 cm.find its curved surface area.

Answer 1

Volume of right circular cylinder=1100

πr2h=1100

22/7*25*h=1100

h=1100*7/22*25

h=14

Lateral surface area = 2πrh

=2*22/7*5*14

=440 m2

Answer 2

Answer:

Given:-

Volume of right circular cylinder = 1100 cm³

It's Base Radius = 5 cm

Solution:-

Volume of right circular cylinder = 1100 cm³

πr²h = 1100 cm³

22/7 × 25 × h = 1100 cm³

h = (1100×7)/(25×22)

h = 14 cm

Now,

Curved surface area of cylinder = 2πrh

=> 2×(22/7)×5×14

=> 440 cm²

Thus, curved surface area of right circular cylinder is 440 cm².
