For a cylindrical pool, the inner wall and bottom of the pool should be inlaid with ceramic tiles. The diameter of the pool bottom is 6 meters, and the pool depth is 1.2 meters. How many square meters is the area inlaid with ceramic tiles?
6/2 =3
(3^2)*3.14=28.26
6*3.14*1.2=22.608
28.26+22.608=50.868
A: the area of ceramic tile is 50.868 square meters
For a cylindrical pool, the inner wall and bottom of the pool should be inlaid with ceramic tiles. The diameter of the pool bottom is 6 meters, and the pool depth is 1.2 meters. How many square meters is the area inlaid with ceramic tiles?
Bottom area = 3.14 × (6 ÷ 2) &# 178; = 28.26 (M2)
Side area = 3.14 × 6 × 1.2 = 22.608 (M2)
Area of ceramic tile = 22.608 + 28.26 = 50.868 (M2)
The diameter of the ground of a cylindrical pool is 8m, and the depth of the ground is 3M,
How many tiles do you need at least?
The radius of the cylindrical tank is 8 / 2 = 4m
Area = 4 * 4 * 3.14 + 8 * 3.14 * 3 = 125.6m2 = 12560m2
Required tiles = 12560 △ 2 = 6280
