Explanation / Answer

1) The diameter of the circle should be the diagonal of therectangle so D^2 = 12^2 + 5^2 D = 13 Circumference = Diameter * Pi, so D = 13 The answer should be (a) 2)Since C = D and C = the Diameter is just 1 andradius 0.5 Area of Circle = r^2 or (0.5)^2 = (1/4) Since area of square = area of circle, the area of square is(1/4) A of square = length^2 so length = sqrt((1/4)) =(1/2)sqrt() Perimeter = 4 * length = 4 * (1/2)sqrt() = 2sqrt() So the answer should be (d) Hope this helps
