Im studying on an exam and im stuck at this question.
The area of circle P is 36pi in^2
If CB=6 in, find the area of triangle ABC?
I know that the angle C is right, is the sides CB and AC equal then?
Plz help!!
No, not necessarily. But you are told that CB= 6 and you can find AB: the area of the circle is $\displaystyle 36\pi= \pi r^2$ so you can find r, then AB. And, of course, you can find CA using the pythagorean theorem.
Hi Julieta,
Previous responders have given you equations for finding either a diameter or radius of given circle You should redraw your improperly drawn triangle in the semicircle and from it calculate the area of triangle.
