Question 261666
if 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?

$60/($3.50/square foot) = $60 * square foot/$3.50
60/3.50 = 6000/350 = 600/35 = 120/7 = 17.142857 square feet approximately maximum for square feet allowed and maximum area of the circular table allowed

pi * r^2 = area of circular table = 17.142857
r^2 = 5.456741 approximately
r = 2.335967 feet approximately maximum radius
