Answer:
r=6
Step-by-step explanation:
The area of a circle is given by πr². Note that this uses the radius, not the diameter.
Now, one quarter of this area (ABC) is given to be 9π.
So apparently:
If you solve this:
(divide both sides by π)
(multiply both sides by 4)
so
r = √36 = 6
so the radius is 6.

Answer:
I think the answer would be ( 2, 5 )
Step-by-step explanation:
The formula for rotating a shape 270 degrees counter clockwise is ( y, -x ) meaning that the original coordinates of B ( -5, 2 ) will become ( 2, 5 ). The 5 is positive because the negatives cancel out. :)
