Write the area of the figure in the attached file in factored form. - Jan 9th 2009, 09:11 AMConstatine11
Cut off the semi-circular ends and join them along the cut. Now you have a square of side 2r and a circle of radius r.

Hence the area of the firgue is equal to the sum of the areas of a square of side 2r and a circle of radius r. Write this out, take out the common factor and you are done.

Hellow, first u huv 2 brin' da area af da square which is

S*S=4r^2 unit^2

plus da area of da identical semi circles

pi*redias^2

=pi*r^2

=3.14r^2

da area of all is: area of square + area of both circles

=3.14r^2+4r^2

=7.14r^2 unit^2

I think dat ez da answer!!!!!!!!!(Headbang)
