Step-by-step explanation:
The area of the circle is
pi *r^2
pi * 12^2
144pi
The part that is shaded is 45 degrees

11. 21
Step-by-step explanation:
I could not see the answer but it should look like this:
11.6-3(3-[2-3]-10)-3
6-3(3-[-1]-10)-3
6-3(3-(-1)-10)-3
6-3(4-10)-3
6-3(-6)-3
6-(-18)-3
(6-(-18))-3
24-3
21
The answer is 1.072, just slide the decimal point over
193.75 divided by 15 = 12.9666....
So the average cost would be $12.96
Because it is much easier to identify the place values when multiplying numbers. You can immediately sight the numbers to be multipied.
An example
