The perimeter of a square is equal to the perimeter of a rectangle of length 17 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)
Pick one: A) 23.57 B) 23.54 C) 23.5 D) 24.35 E) 24.51
Let the side of the square be a cm.   Perimeter of the rectangle = 2(17 + 14) = 62 cm   Perimeter of the square = 62 cm   i.e. 4a = 62   A = 15.5   24.35iameter of the semicircle = 15.5 cm   Circumference of the semicircle   = 1/2(∏)(15.5)   = 1/2(22/7)(15.5) = 24.35 cm to two decimal places   Answer: 24.35
