Baseballs have a radius of 9 cm. Find the volume of 5 balls.?

4/3(pi)(9)^3 = 3053.64cm^3 = Volume of one baseball
3053.64(5) = 15268.2cm^3 = Volume of five baseballs <= answers

V = [ (4/3) π x 9 ³ ] x 5 cm³

V = [ 12π x 81 ] x 5 cm³

V = 4860 π cm³

The formula for volume of a sphere is V=(4/3) * pi * r^3

If you have 5: V = 5 * (4/3) * pi * (9cm)^3

V = 20/3 * pi * 729cm^3 = 4,860pi cm^3 =~ 15 268.14 cm^3.
We can get this into cubic metres if you want by dividing by 100^3 = 1 000 000

So V = 0.015268 m^3

A baseball is a sphere with radius r = 9 cm.
volume of sphere = (4/3)πr³ cm³
volume of 5 baseballs = 5(4/3)πr³ cm³
