Question

A circular table is to be made that will have a top covered with material that costs $3.50 per square foot. The covering is to cost no more than $60. What is the maximum radius for the top of the table?

Answer 1

The formula for the area of a circle is \[A=\pi r^2\]
Total cost will be \(A * $3.50/ft^2\)Set total cost to $60 and solve for \(r\).
