A student is trying to calculate the density of a ball. She already knows the mass, but she needs to determine the volume as wel
l. Which of the following formulas can be used to calculate the volume of the ball? V equals four-thirds times pi times r cubed
V equals one-third times pi times r squared times h
V = s3
V = πr2h
Let's examine the given choices: V = (4/3)*pi*(r)^3 is the rule to calculate the volume of the sphere V = (1/3)*pi*(r)^2*h is the rule to calculate the volume of the cone V = s^3 is the rule to calculate volume of the cube V = pi*(r)^2*h is the rule to calculate volume of the cylinder
Now, the ball can be treated as a perfect sphere, therefore, to calculate its volume we will use the rule of the volume of sphere.
Based on this, the correct choice is: V = (4/3)*pi*(r)^3
