A spherical paintball measures 1.5 centimeters in diameter. Approximately how many paint is in it?
valentinak56 [21]
For this case, what we must do is find the volume of the sphere, which will be given by:
 V = (4/3) * (pi) * (r ^ 3)
 Where,
 r = radius of the sphere
 Substituting the values we have:
 V = (4/3) * (pi) * ((1.5 / 2) ^ 3)
 V = 1.767145868
 Round:
 V = 1.78 cm ^ 3
 Answer:
 
There are approximately 1.78 cm ^ 3 of paint.
