The density, p, of an object can be calculated using the formula p=\dfrac{m}{V}, where m is the mass of the object and V is its volume. The volume of a sphere can be calculated using the formula V=\dfrac{4}{3}\pi r^3, where r is the radius of the sphere. Which of the following equations could be used to find the radius of a spherical object given its mass and density?

A)
B)
C)
D)

substitute m/p =v, so now m/p = 4/3pi r^3
flip flop gonip ginop the 4/3pi on the other side of equal sign, but leave behind the cube root radius
3m/4p.pi= r^3
perform cube root canal to get the radius by itself, since that is what they are asking for
(3m/4p.pi)^1/3 = r
