A CIRCULAR COFFEE TABLE HAS A DIAMETER IF 5FT. WHAT WILL THE COST BE TO BE REFINISHED IF THE COMPANY CHARGES $3.00 PER SQUARE FOOT?
A+=+pi%2Ar%5E2
r+=+2.5
A+=+pi%2A2.5%5E2
A+=+pi%2A6.25
A+=+19.635 ft2
If cost = C
C+=+3%2A19.635
C = $58.90 answer

Correct!
Note that the area of a circle can be
either
πr² or πd²/4
Total cost
=πr²*($3)
=π(d²/4)*($3) 
Thank you MathMate,
you're a life saver 
I love those candies with a hole in the middle! :)
