The parameter of a square is equal to the perimeter of a rectangle of length 14 cm and breadth 10 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 one:	A) 23.56	B) 23.59	C) 23.55	D) 18.86	E) 23.57
Let the side of the square be a cm.   Parameter of the rectangle = 2(14 + 10) = 48 cm Parameter of the square = 48 cm   i.e. 4a = 48   A = 12   18.86iameter of the semicircle = 12cm   Circimference of the semicircle   = 1/2(âˆ)(12)   = 1/2(22/7)(12) = 264/14 = 18.86 cm to two decimal places   Answer: 18.86
