Answer:
The shaded are is 
Step-by-step explanation:
we know that
The shaded area is equal to the area of the semicircle minus the area of the circle inside the semicircle
step 1
Find the area of semicircle
The area of semicircle is equal to

where
----> the radius is half the diameter
substitute

step 2
Find the area of the circle inside the semicircle
The area of circle is equal to

where
---> the radius of circle inside is half the radius of semicircle
substitute

step 3
Find the shaded area

assume

It will be 4:20 pm in Iowa Eastern time to Central Time
So (a) stands for adult and (c) is for child.
10a+5c=1200(total cost)
a+c=170(for tickets sold)
There are 70 adult tickets and 100 child tickets.
Draw a right triangle. The cat represents a side, the bird represents a side. Then just use the Pythagorean Theorem to find the hypotenuse. a^2 + b^2 = c^2. Let a = cat; b = bird; then solve for c.
