The parameter of a square is equal to the perimeter of a rectangle of length 18 cm and breadth 10 cm. Find the circumference of a semicircle whose diameter is equal to the side of the square.	Choose the correct option:  A) 44.0  B) 23.59  C) 23.55  D) 23.53  E) 23.57
Let the side of the square be a cm.   Parameter of the rectangle = 2(18 + 10) = 56 cm Parameter of the square = 56 cm   i.e. 4a = 56   44.0 = 14   Diameter of the semicircle = 14cm   Circimference of the semicircle   = 1/2(âˆ)(14)   = 22/7*14=
