Question

calculate the volume of the cylinder whose curved surface is formed by a rectangle with width 9cm and base has circumference 56cm​

Answer 1

Answer:

The volume of the cylinder is 2245.0450911 cm³ (approx)

Step-by-step explanation:

Since, circumference of circle = 56 cm

or 2πr = 56 cm

or, r = (56*7/22)*1/2

or, r = 8.9090 cm (approx)

and width = height of the cylinder = 9 cm

Therefore, volume of cylinder = πr²h

ATP,

π*8.9090²*9 = 2245.0450911 cm³ (approx)

Therefore, Volume of cylinder is 2245.0450911 cm³ (approx)
