(PLEASE HELP! WILL GIVE BRAINLIEST TO THE CORRECT ANSWER!) Estimate the fraction of a circle's area that would be represented by r^2. Explain how you arrived at this estimation, drawing a diagram if necessary.

Solve - pv + 40 < 65 for v solve 7w - 3r = 15 for r

Does anyone know how to do geometryme with this problem
