Step-by-step explanation:
To give you a hand for this question, I will show you how to work out one of the equations
One equation is 
We know that when x = -2, y = 6
So we can substitute in -2 and see if we get 6





So this equation is true! Now try the same for the other equations :)
It’s 1, anything to the zero power is one.
So I don’t have a step by step answer but I’m pretty sure it’s Area- =2461.76cm2 r= 28 but idk I just looked it up
