To calculate the cost of fencing the circular park, you need to determine the length of the circular fence and then multiply it by the rate of $7 per foot.
Calculate the circumference of the circular park, which will be the length of the fence needed. The circumference of a circle is given by the formula:
Circumference = π * Diameter
Given that the diameter is 150 feet and using π = 3.14:
Circumference = 3.14 * 150 feet = 471 feet (rounded to the nearest foot)
Now that you have the length of the fence, you can calculate the cost. The rate is $7 per foot:
Cost = Length of Fence * Rate
Cost = 471 feet * $7/foot
Cost = $3,297
So, the cost of fencing the circular park is $3,297.
