<span>first thing you need to do is find the area of the circle
A=(pi)r^2
You don't know r, but you do know the diameter is 10, and the diameter is twice the radius so r=5
Then plug that into the area formula, and you'll get A=25pi or 78.54 ft^2
If one bag covers 2 ft^2, then divide your area by 2 and round up to get the number of bags of concrete (40)
