Question

the volume of a right circluar cylinder is 1100cm3 and the radius of its base is 5cm find its ccurved surface area

Answer 1

volume : πr²h =1100
h=(1100*7)/5*5*22
h=14cm
now, curved surface area=2πrh
2*(22/7)*5*14
440 cm²
hope this helps you

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.
