Answer:

V = \frac{4}{3} \pi R^{3} and

v = \frac{4}{3} \pi r^{3}

Step-by-step explanation:

Dawn wants to compare the volume of a basketball with the  volume of a tennis ball.

Now, if the radius of the basketball is R and that of the tennis ball is r, then the formula that can be used to determine the volume of each ball will be

V = \frac{4}{3} \pi R^{3} and

v = \frac{4}{3} \pi r^{3}

Now, dividing V by v we can compare the volume of the basketball and the tennis ball. (Answer)
