18. Julie works at the amusement park with the maintenance crew. She needs to replace a string of burnedout lights along the arc shown between seat 1 and seat 6. The arc makes up 1/4 of the Gaint Wheel. The 20 seats of the wheel are equally spaced, and the supports from the center of the wheel to each seat are 15 feet in length. How long, to the nearest foot, does the string of replacement lights need to be? Seat 6 15 feet Seat 1 Gaint Wheel (A) 24 feet (B) 30 feet (C) 47 feet (D) 90 feet
Here the arc is quarter of giant wheel radius is 15 feet so perimeter of 1/4th wheel which is length of arc is = Pi.*15 /4 = 24 feet - regards Ramesh
