Step-by-step explanation:

15 - c = 6
15 - 6 = c
9 = c
c = 9
I'm assuming a quarter-circle is exactly 1/4 of a circle. Thus if you have 4 congruent quarter-circles, that should mean they make a complete circle.
If that is the case, then we can find the area of the full circle using pi*r^2.
So the area of the circle is 5^2*pi or 25pi.
To find the area of the shaded region, we subtract the area of the circle from the area of the square.
The area of the square is 10^2 or 100.
So the area of the shaded region is 100 - 25pi.
My calculator says that equals roughly 21.46

Answer:
$9.00
Step-by-step explanation:
~~~~Hey there~~~~
1. Since it was 15% discount, that means you have to solve 15% of 60, which is equivalent to 0.15 x 60.
2. Since the product of 0.15 and 60 is 9, then 9 is your answer.
3. Your final answer is $9.00
Hope this helped!

(a) 28%
(b) 24%
When calculating the total amount of people it come out to 150.
According to the table 42 people smoke. 42/150 is 28%
According to the table 36 people exercise regularly. 36/150 is 24%
