An archery target consists of five concentric circles. Points for each region on the target are indicated. The radius of the bul
l’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.

Answer:
625 minutes
Step-by-step explanation:
Given that:
Time taken to tie 4 ribbons = 10 minutes
Number of ribbons to be tied = 250
To find:
Time taken to tie 250 ribbons.
Solution:
First of all, we need to find the time taken to tie one ribbon.
And then we can multiply it with 250 to find the time taken to tie all the 250 ribbons.
For finding the time to tie one ribbon, we need to divide the time taken to tie 4 ribbons with 4.
Time taken to tie 1 ribbon = minutes
Time taken to tie 250 ribbons = 2.5 250 = <em>625 minutes</em>
