length in cm =

height in cm =

My attempt on find the relationship between the rectangle and the quarter circle:

Let the base of the rectangle = b

let the height of the rectangle = h

Area of a a rectangle = b*h

Area of a circle =pie*R^2

Quarter of a circle = 1/4 pie R^2

am I on the right track......

is this the correct thought process....

**Ashley**, Tuesday, January 29, 2013 at 8:52amWould it be safe to say that the the diagonal line in the rectangle could equal r = 2.

so I could use

b^2+ h^2 =r^2

solve for h

h= Square root ( r^2 -b^2)

Area = b^2 * Square root (r^2-b^2)

area = b*(r^2-b^2)^1/2 ....... ????

so is next step take the first derv of the area

Area of rect '= -1/2(4-b^2) + (4-2^2)^1/2
