A circular coffee table has a diameter of 5 ft. What will it cost to have the
top refinished if the company charges $3 per square foot for the refinishing?
Didn't you see my previous answer???

thanks sorry i did not catch that
To calculate the cost of refinishing the circular coffee table, you first need to find the area of the table's top. The formula for the area of a circle is A = πr^2, where A represents the area and r represents the radius of the circle.
Given that the diameter of the table is 5 ft, the radius can be calculated by dividing the diameter by 2: r = 5 ft / 2 = 2.5 ft.
Now, substitute the value of the radius into the formula to find the area: A = π(2.5 ft)^2.
To evaluate the equation, you need the value of π (pi), which is approximately 3.14159. Plugging in the values, you get A ≈ 3.14159 × 2.5 ft × 2.5 ft.
Calculating further, you find that A ≈ 19.625 ft^2.
Now that you have the area of the table top, you can determine the cost of refinishing. Given that the company charges $3 per square foot, you multiply the area by the cost per square foot: cost = 19.625 ft^2 × $3/ft^2.
Calculating further, you find that the cost to have the circular coffee table top refinished would be approximately $58.88.
