An archery target consists of five concentric circles. Points for each region on the target are indicated. The radius of the bull’s-eye is 4.5”, and each ring surrounding it is 4.625” wide. Round to the nearest hundredth.
a.) What is the area of the bull’s-eye?
b.) What is the area of the seven-point region?
c.) What is the area of the entire target?
d.)The probability of hitting the bull’s-eye on a random shot that hits the target is:
P(bull's eye)=area of bull's eye/area of target
e.)Calculate the probability of hitting the bull’s-eye. Express your answer as a percent. This gives the percentage of the time in which a shot that hits the target at random would be expected to hit the bull’s-eye.
