A football can occupy 36π $$cm^3$$​of air. Its radius (in cm) will be:

Correct option is D

Given:

Volume of football = $$36\pi cm^3$$​​

Formula Used:

Volume of sphere =$$\frac{4}{3} \pi r^3$$​​

Solution: 

Volume of sphere = 36$$\pi$$​​

​$$\frac{4}{3} \pi r^3 = 36\pi$$​ 

​$$r^3 = \frac{36 \times 3}{4}$$​

​$$r^3 = 27$$​​

​$$r= \sqrt[3]{27}$$​​

r = 3cm
