Rafael is building a circular table with a diameter of 2.5 feet. The wood costs $32.50per square foot. How much will it cost Rafael to make the table?

Answer 1

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
