Given : Room with dimension 6 by 4 m
Circular tile with 50 cm diameter
To Find : Number of circular tiles along length
Total number of tiles
Area covered by each circular tile.
Solution:
Length of room = 6 m
1 m = 100 cm
Hence length of room = 6 * 100 = 1600 cm
Diameter of tile = 50 cm
Number of tiles along length = 600/50 = 12
Number of tiles along width = 4 * 100/50 = 8
Total number of tiles = 12 * 8 = 96
Diamter of tile = 50 cm
radius of tile = 50/2 = 25 cm
Area of a circle = π (radius)²
Area of a tile = π (25)²
π = 22/7
Area of a tile = (22/7) (25)² = 1964.28 cm²
