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?
First, find the circumference of the circle with diameter 5 feet.
We use this formula:
C = pi x d, where pi = 3.14 and d = 5 feet
C = 3.14 x 5 feet
C = 15.7 feet
Now multiply 15.7 feet by $3 and you will find how much it will cost to have the top refinished.

To calculate the cost of refinishing the circular coffee table, we need to find the area of its top surface.
1. The diameter of the circular coffee table is given as 5 ft.
2. The radius of the circular coffee table can be calculated by dividing the diameter by 2.
Radius = 5 ft / 2 = 2.5 ft.
3. The formula to calculate the area of a circle is: A = π * r^2, where A is the area and r is the radius.
Area = π * (2.5 ft)^2 = 3.14 * (2.5 ft)^2 = 3.14 * 6.25 ft^2 = 19.625 ft^2.
4. The company charges $3 per square foot for refinishing.
5. The cost of refinishing the circular coffee table can be calculated by multiplying the area by the cost per square foot.
Cost = 19.625 ft^2 * $3/ft^2 = $58.875.
Therefore, it will cost $58.875 to have the top of the circular coffee table refinished.
To find out the cost of refinishing the circular coffee table, we need to calculate the area of the table top. We know that the table has a diameter of 5 ft, which means the radius (half of the diameter) is 5 ft / 2 = 2.5 ft.
The area of a circle is calculated using the formula: A = πr^2, where A represents the area and r is the radius.
Calculating the area of the circular table: A = π(2.5 ft)^2 = π(6.25 sq ft) ≈ 19.63 sq ft.
Now, since the company charges $3 per square foot for refinishing, we can multiply the area of the table by the cost per square foot to get the total cost.
Total cost = 19.63 sq ft * $3/sq ft = $58.89.
Therefore, it will cost approximately $58.89 to have the top of the circular coffee table refinished.
