Given:
Length of the sheet = 220
Width of the sheet = 150
To Find:
The volume of cylinder
Solution:
Circumference of top = 2πr
Therefore,
r = 220/2π
Now,
Volume = πr²h
Therefore -
π × ( 220/2π)² × 150
= 220 × 220 × 7 × 22 / 4 × 150
= 11 × 110 × 7 × 22 /15
= 11 × 22 × 7 × 22 /5
= 7453
Answer: The volume of cylinder is 7453.6 cm³
