Janelle and Sandra are planting various colors of flowers in a circular shape on the front lawn of their university to display the school\'s new logo. The circle has a diameter of 18 feet and the flowers cost $16.00 per square yard. Find the cost of the flowers. The cost of the flowers for the new logo is approximately $ .

Solution

Radius of Circle = Diameter/2 = 18 ft/2 = 9 ft

Area of the Circle = pi * r^2 = 22/7 * (9)^2 = 254.571 feet^2

1 feet^2 = 0.111111 yd^2

Hence area of circle in yards = 254.571 feet^2 * 0.111111 yd^2/1 feet^2 = 28.285 yd^2

Cost of flowers required = 28.285 yd^2 * $16.00/yd^2 = $452.57
