Can Someone help with problems 4 and 5?
Problem 4. A circular-shaped archery target has three concentric circles painted on it. The in- nermost circle has a radius of 1/V3 feet, the middle has a radius of 1 foot, and the outermost circle has a radius of v3 feet. An arrow hitting in the innermost circle counts for 4 points, between the in nermost and middle circle 3 points, between the middle and outermost circle 2 points, and not hitting...
