The famous rotunda of the Capital Bldg has a floor that is 96 feet in diameter. A marble restoration company charges $40 per sq. yard for its services. How much would it cost to restore the entire floor in the rotunda?

My answer 96 feet in diameter C=πd
96+3.14π=105.9

1 answer

No
They are chargint $40 per <b<square yard, so we are dealing with area, not circumference

Area = πr^2
= π(48)^2
= 2304π feet ^2
= 256π yards^2

cost = $40(256π)
= $32,169.91

or appr $32,170

Your answer of only $105.90 should have sounded totally unreasonable to you .
