The figure represents a piece of land that is in the shape of a quarter circle. If the land is enclosed by a fence , which of the following is the closest to the length , in feet, of the fence?
OA ----> C
Wish I got this on my gmatprep. If u know the rules of circles and what not, this is a gimme problem.
Essentially the question is asking us for the perimeter of the quarter circle.
P= Side1+side2+arc length of the 1/4 circle. radius is 100ft so the diameter is 200ft.
to find the arc length take the degrees of the center of the circle given here as 90degrees and divide it by the total degrees of the circle. So 90/360=1/4.
P=100+100+50pi ---> 200+50pi. U must know that pi is rougly 3.14 or even just 3. so 200+150=350. Closest answer to this is C.
