Answer:
so um your answer is in step by step
Explanation:
I assume you just want to calculate the cost of making a circle with a diameter of 2.5 feet.
The area of a circle can be calculated using the following formula: A = pi * r2
The radius of a circle is half of the diameter. For this problem, the radius will be 2.5 / 2 or 1.25 feet and pi is 3.14
Then the area will be : A= 3.14 * 1.252
A= 3.14 * 1.5625 = 4.90625 ft2
If each square foot cost $32.50, then the wood will cost $32.50 * 4.90625 = $159.45
