<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>
Answer:
the black-coloured sand found in Fujairah may be specific to dark-coloured mountain regions in the emirate and the white-coloured sand is found close to the RAK mountains because of the presence of sandstone. there are my colours of sand present in all over the emirates of UAE. this maybe one of the reasons for which some mountains compared to others may differ in colour.
