The diagonals of a rectangle have equal lengths. The area of the circle shown is 25(3.14) m^2. Find the?

Question

approximate radius of the circle. For the rectangle shown, what is the length of diagonal BD? What is the length of diagonal AC?
(Please show your work because according to my book, r=BD=AC=5m. Thank you!)

Answer 1

(3.14)r^2 is pretty much the formula for circle area.

(3.14)r^2 = 25(3.14) m^2
r^2 = 25 m^2
r = 5 m
So the approximate radius of the circle is 5 m. I don't see the rectangles though.

You show YOUR work and we'll help you if you go wrong somewhere. Also -- it's kinda hard to visualize the "shown" elements of this equation without the picture.
