Question 1027631: I have the coordinates -5, -4 and 3, 2 that sit on opposite ends of a circle's diameter. What is the area of the circle? How can you find the diameter without a compass? Found 2 solutions by rfer, MathTherapy:Answer by rfer(16322) (Show Source):
You can put this solution on YOUR website! Use the Pythagorean Theorem to find the diameter.
a^2+b^2=c^2
6^2+8^2=c^2
c=sqrt of 100
c=10.
That is the diameter.
---------------------
a=3.14r^2
a=3.14*5^2
a=3.14*25
a=78.5 sq un
