The circumference of the base of a cylinder is 66 cm and it's height is 40 cm. find the volume of the cylinder
Answers
Answer: The volume of the cylinder is 13860cm^3
Step-by-step explanation:
Given,
circumference of the base of cylinder=66cm
Height of cylinder=40cm
Formula using
circumference of a circle=2πr
Where, r=Radius of circle
Volume of cylinder=πr^2
Solution
2πr=66cm
2x22/7xr=66cm
r=(3x7)/2cm
r=21/2cm
volume of cylinder=π(21/2cm)^2x40
22/7x441/4x40cm^3
220x63cm^3
13860cm^3
Therefore, The volume of the cylinder is 13860cm^3
Answer:
Circumference = 2πr
66 = 2 × 22/7 × r
r = 66 × 7/2
r = 10.5cm
Volume of cylinder = πr²h
= 22/7 × 10.5 × 10.5 × 40
= 22/7 × 4410
= 972020/7
= 13860cm³
