Step-by-step explanation:
elimination
There were 72 adult tickets sold.
I used the elimination method to solve this.
-918.55
M (0, 6)
By midpoint formula,
M [(x1+x2)/2 , (y1+y2)/2]
M [-5+5/2 , 3+9/2]
M (0/2 , 12/2)
A =12.56 units^2
The area of a circle is found by
A = pi r^2
We know the radius is 2
A = pi (2)^2
A = 4pi
Using 3.14 as pi
A = 4(3.14)
