<PRE><B>Question 274512</B>
the other tutor forgot to convert from ft^2 to yd^2
Sarah bought a circular marble table top...its 12 ft in diameter. at $90 per square yard how much did sarah pay for the table top?
solution
you need to find the area of the table for it.
if diameter = 12ft, radius = 6ft
area = pi*r^2
= 3.14*6^2
= 3.14*36
divide by 9 sq ft to get sq yards

now, to find how much sarah paid, $90*3.14*4=$1130.40
