Y=2x-10
Y=4x-8 
U substitute it and it turns into 2x-10 =4x-8
U get x=-1 
Y=4*(-1)-8
Y=-12
(x,y)= (-1,-12)

First, let's find the area! The formula to find the area of a circle is πr²
πr²
3.14 · 4²
50.24 yds²
Now let's find the circumference. The formula for this is 2πr
2πr
2 · 3.14 · 4
25.12 yds
Hope this helps!
