The perimeter of a square is equal to the perimeter of a rectangle of length 15 cm and breadth 14 cm. Find the circumference of a semicircle whose diameter is equal to the side of the square. (Round off your answer to two decimal places) Choose the correct choice from the following answers:	A) 22.78	B) 23.54	C) 24.5	D) 25.55	E) 23.51
Let the side of the square be a cm.   Perimeter of the rectangle = 2(15 + 14) = 58 cm   Perimeter of the square = 58 cm   i.e. 4a = 58   22.78 = 14.5   Diameter of the semicircle = 14.5 cm   Circumference of the semicircle   = 1/2(∏)(14.5)   = 1/2(22/7)(14.5) = 22.78 cm to two decimal places   22.78nswer: 22.78
