scarlett_feathers · Answer

they don't teach me theses things! they just throw the problem at you and say figure it out your own damn self. Which leads me to this site....

so the perimeter of this rectangle you get assuming these two length and two width 
but the second width include the diameter of semicircle - yes ? so than you calculi without it

scarlett_feathers · Answer

the length of the rectangle is assumed to be the full diameter of the circle

scarlett_feathers · Answer

circumference is pi*radius^2
