Answer:
A =63.585 in^2
Step-by-step explanation:
The area of a circle is found by
A = pi r^2
A = pi (4.5)^2
A = pi(20.25)
We can approximate pi by 3.14
A = (3.14) (20.25)
A =63.585 in^2
Note that 60 minutes is 1 standard deviation away from the mean and from recalling the 68-95-99.7 rule, the area that will remain is (100 - 68) = 32%. However, we only want the leftmost portion of this area, so the answer is 32%/2 = 16%.
