What is the area of a triangle that has a 270 degree angle within a circle whose radius is 4 inches?

I know the area of a circle is pie*radius(squared), so what would be the area and if you could please tell me how you got the answer thanks

270 degrees is 3/4 of a circle. So the area would be 3/4 * pi * r^2

The area is 12pi.Hope this helped.
