Question

A basketball has a surface area of 1810cm2 Find the radius of the basketball and the volume of air in it

Answer 1

a basketball has a surface area of 1810cm^2 find the radius of the basket ball and the volume of air in it
**
surface area of sphere=4πr^2=1810
r^2=1810/4π
r≈√(1810/4π)≈12.00 cm
..
volume of sphere=4/3*π*r^3=7238.23 cm^3
ans:
radius of basket ball≈12.00 cm
volume of air in it≈7238.23 cm^3
