Question 242605
Are you saying that a circle is contained within a rectangle that is 22 cm by 15cm?  If so, then the largest circle that can be contained within the rectangle will have a diamster equal to the width of the rectangle.  This means that the radius of the circle is HALF the diameter which is 15/2 cm or 7.5 cm.


The area of the circle is {{{pi*r^2= pi*(15/2)^2}}} or {{{pi*7.5^2}}}


The area that is left in the rectangle after the circle is cut out will be the total area of the rectangle (L*W = 22*15) MINUS the area of the circle.


AREA OUTSIDE THE CIRCLE = {{{22*15 - pi*7.5^2}}} sq cm.   Do you have a calculator??  I don't have mine with me right now, so you'll have to do the calculation!!


The formula for this will be {{{L*W-pi*(W/2)^2}}} sq cm.
