The volume of a cylinder having height 21 cm and radius 10 cm is:
(Use π = $$\frac{22}7$$​)

Correct option is B

Given: 

Radius of cylinder = 10 cm

Height of cylinder = 21 cm

Formula Used: ​

Volume of cylinder = $$\pi r^2h$$ 

Solution: ​

Volume of cylinder = $$\frac{22}{7}\times (10)^2 \times 21 = 22 \times 100\times 3 = 6600 cm^3$$​​
