The dog spa in Champlin has an outside play area. Each play area is in

the shape of a circle and divided into four equal sections with a radius of

18 feet long. The spa wants to install fake grass that will cost $12.50 per

square foot. How much will it cost to put fake grass in only one of the four

play areas?

Answer: $12,723.45

Step-by-step explanation:

Details of each play area:

The radius of circle = 18 feet long

Cost of fake grass per square foot = $12.50

Therefore,

We can obtain the Area of the play area by calculating the area of the circle:

Area of a circle = πr^2

Area = π * 18^2

Area = 1,017.876ft^2

Since the cost per square foot is $12.50

Therefore, Cost of 1,017.876 ft^2 equals

Cost per square foot * Area of play area

($12.50 * 1,017.876)

= $12,723.45
