Question

A spherical paintball measures 1.5 centimeters in diameter. Approximately how many paint is in it?

Answer 1

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.
