Use 3.14 for Pie. Use v=pie x radius squared x height

A cylindrical water tank has the radius of 5m and a height of 10 m. The volume of water in the tank is 565.2 cubic meters
the height of the water in the tank is 7.2m
b) What percent of the tank is filled with water?

1 answer

First, we can use the formula v=3.14 x radius squared x height to find the total volume of the cylindrical tank:

v = 3.14 x 5^2 x 10
v = 785 cubic meters

Next, we can divide the volume of water in the tank by the total volume of the tank and multiply by 100 to find the percentage of the tank filled with water:

percentage filled = (565.2/785) x 100
percentage filled = 71.97%

Therefore, the tank is 71.97% filled with water.
