Wait just a second, what's the radius of the circle anyway?
well, the radius is the segment going from the center of the circle to the circle itself, well, low and behold, if we just get the distance from those two points, that gives us the radius.

A because you have to add positive six to both sides to cancel the six out.
Answer:
<u>27π units²</u>
Step-by-step explanation:
The rest of the question is the attached figure.
This shape represents (3/4) of a full circle.
So, find the area of a full circle with radius 6 units, then multiply the result by 3/4 to obtain the area of the given shape.
Area of full circle = π r²
So, Area of full circle = π(6)² = 36π units²
Then the area of the given shape is = <u>(3/4)(36π) = 27π units²</u>
Hello!
500 millimeters = 0.0005 liters.
(for volume)
Enjoy.
