To determine how many 50 lb bags of sand are needed to cover a 15-foot round area, first calculate the area of the circle using the formula ( A = \pi r^2 ). The radius ( r ) is 7.5 feet, so the area is approximately 176.71 square feet. If you assume a depth of 1 inch for the sand, you will need about 0.5 cubic yards of sand, which is roughly 13-14 bags of 50 lb sand, depending on the sand's density and compaction.

To cover a 27-foot round circle, first calculate the area of the circle using the formula (A = \pi r^2), where (r) is the radius (13.5 feet). This gives an area of approximately 570.58 square feet. Each 4'x8' square has an area of 32 square feet. Dividing the area of the circle by the area of one square, you will need about 18 squares to cover the circle.
To determine how many 2x2 tiles fit in a 10ft x 15ft room, first calculate the area of the room, which is 10ft x 15ft = 150 square feet. Each 2x2 tile covers an area of 4 square feet. Dividing the room's area by the tile's area gives 150 square feet ÷ 4 square feet/tile = 37.5. Since you can't have a fraction of a tile, you can fit a maximum of 37 tiles in the room.
