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)
