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)
