19.63 square inches.
The area of a circle can be found with the formula (pi)r2. Since r = d/2, r would be 8in in this case. A = 64pi in2, or 201.1in2
Radius = Diameter/2. So in this case, radius = 8in/2 = 4 in

You use the formula A=(pi)r^2 solve for r which will give you the square root of A/pi. In your case the area has pi already in it so it is just 2 times the square root of 8.

5ft 8in to be exact

The area of square is : 64.0

The surface area of a cylinder that has a radius of 6 in and height of 8in is 527.8 square inches.
It is: 0.5*8*8 = 32 square inches
4 inches The radius of a circle is always half of its diameter (so 8in/2 = 4 in).
Answer depends on the dimensions of the room. assuming that both the tiles and the rooms are squares, number of tiles = area of room/area of one tile =(80ft)^2/(8in)^2 =((80*12inch)/8in)^2 =14400
