<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)
hope i helped !!!</span>
It is most likely to form a sedimentary rock due to it exposing to weather on a surface. When a rock is on surface, it may be eroded by weathering such as rain and wind, which cause it to loose fragments. The fragments will then be carried down to river by moving agents or gravity, sedimentation or deposition will then occur, the overlaying layers compacting the fragments into a solid rock after the process of lithification and cementation in which rocks are bind together by minerals dissolved such as silica and calcite.
Geography would be useful planning because it helps the builders determine where certain public facilities, such as parks and restaurants, and transportation, and buildings would be located.
