You can put this solution on YOUR website! 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
= 113.04 ft^2
now, to find how much sarah paid, $90*113.04
= $10,173.6

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
