Answer:
You can't have a single answer.
Step-by-step explanation:
An indiviual equation can't be solved if it has 2 variables.
You can, however, graph it.
The line will create all the possible sets of answers for the problem.
P(x)=-4(x-15)2+2
P(x)=7
P(7)=-4(7-15)2+2
-4*7-4*-15
P(7)=-28+60+2+2
P(7)=92
The area of a circle is A=pi(r)^2. Since the diameter is 13, the radius would be 6.5. Doing the formula (3.14)(6.5)^2, the answer would be 132.665.
360 it an area of the circle
