Answer:
402.1 in^2
Step-by-step explanation:
Find the area of the circle with the 18 in. radius first.
Formula for a circle is πr^2
So the area of the circle with the 8 in. radius is 1017.9 in^2
Now do the same for the 14 in. radius circle.
The area for the 14 in. radius circle is 615.8
Now subtract:
1017.9 - 615.8 =
402.1 in^2

Answer:
10.35mi/hr
Step-by-step explanation:
Let's first convert feet to miles:
5280 ft = 1 mi
63,756 ft =12.075 mi
Now let's convert minutes to hours:
60 minutes = 1 hr
70 minutes = 1.167 hr
Now we find the rate in miles per hour:
12.075mi/1.167 hr=10.35mi/hr
