Area of pond:
A=
r=1,5m
A=3,142*1,5*1,5=7,0695
Area of pond with path
B=
r=50 cm+1,5m=0,5m+1,5m=2m
B=3,142*2*2=12,568
Area of path:
12,568-7,0695=5,4985=5,50

Answer:
Step-by-step explanation:
You need to use vertex form of a quadratic to solve this.
Consider the vertex to be
Another way of representing a quadratic is in "vertex form":
Now all you have to do is solve for a. You know that the vertex is and you have know the point of
. Now, all you have to do is plug in these values and solve for a.
Now you know the equation is , but you need it in quadratic form. All you have to do is solve is distribute the 6:
You get:
a = 6
b = 0
c = 2
