The diameter of the patio is 15m . r=7.5m

Area of circle = pi*r^2
Area = pi*(7.5)^2 =176.7 ~ 177
One bundle of paving stones covers 120 sq. ft.
Kristen has ordered 12 bundles of paving stones.
Now you decide.
Check coverage per bundle

Dear tutor mananth,

please read the problem and see that the diameter (and hence the radius) is given in meters, while other dimensions are given in feet.

It is not for the first time I observe that you start solving the problem even without reading attentively the condition.

I have no enough physical strength to fix after each and every tutor at this forum . . .

---------compute this number of square feet for the patio.
