Question

If the radiua of sphere 2r,then what is volume

Answer 1

Answer :-

Given :-

• Radius = 2r

To find :-

• Volume

Solution :-

Volume of sphere = $\sf \dfrac{4}{3} \pi r^3$

According to the question :-

$\sf r = 2r$

Substituting the value :-

Volume of sphere = $\sf \dfrac{4}{3} \pi (2r)^3$

$\sf = \dfrac{4}{3} \pi 8r^3$

$\sf = \dfrac{32}{3} \pi r^3$

Additional information :-

• Volume of a cube = a³
• Volume of a cylinder = πr²h
• Volume of a cone = 1/3πr²h
• Volume of a sphere =4/3πr²
• Volume of a hemisphere = 2/3πr²
