Question

3. The radius of a basketball is approximately 12.1cm. What is the volume of the basketball

A 7359 cm3
B 1840 cm
C. 7421 cm
D. 22 262 cm​

Answer 1

I am thinking C might not be c

Answer 2

The volume of a perfect ball is
`V=(4\pi r^3)/(3)`.

In your case

`V=(4\pi 12.1^3)/(3)=7420.7\approx7421\mathrm{cm^3}`

Hope this helps.
