If the diameter and the height of a cylinder are 12cm and 10.5cm, respectively, then using π = $$\frac{22}7$$​, find the volume of the cylinder:

Correct option is B

Given:

Diameter of Cylinder = 12

Height of Cylinder = 10.5

Formula used: 

Volume of Cylinder = $$\pi r^2 h$$ 

$$\pi = \frac{22}{7}$$ 

r = Radius

h = Height

Solution : 

Diameter of cylinder  = 12 cm

​​$$r = \frac{Diameter}{2}$$ 

$$r = \frac{12}{2}$$  $$= 6cm$$  

Thus, 

$$Volume = \frac{22}{7}\times(6)^2 \times 10.5$$  

$$Volume = \frac{22}{7}\times 378 = \frac{8316}{7} = 1188cm^3$$ 

So, the Volume of Cylinder is  $$1188 cm^3$$
