Choose the answer which best describes how these formulas are related to each other.

• They both solve for circumference. In the first formula it uses diameter, in the second formula it uses two times the radius, which is the same thing as diameter.

• They both solve for circumference, in the first uses diameter and the second uses pi.

• They both solve for area. In the first formula it uses diameter, in the second formula it uses two times the radius, which is the same thing as diameter.

• They both use circumference to solve for pi. One uses radius, the other uses diameter.
