Calculating the Volume of Air Trapped Inside a Cylinder with a Conical Cap
To calculate the volume of air trapped inside the given container, we need to find the volumes of the cylinder and the conical cap separately, and then subtract the volume of the cap from the volume of the cylinder.
Volume of the Cylinder:
The volume of a cylinder can be calculated using the formula V = πr²h, where V is the volume, r is the radius, and h is the height.
Given:
Radius of the cylinder, r = 7 m
Height of the cylinder, h = 10 m
Using the formula, we can calculate the volume of the cylinder as follows:
V_cylinder = π(7²)(10)
= 1540π m³
Volume of the Conical Cap:
The volume of a cone can be calculated using the formula V = (1/3)πr²h, where V is the volume, r is the radius, and h is the height.
Given:
Radius of the conical cap, r = 10.5 m
Height of the conical cap, h = 9 m
Using the formula, we can calculate the volume of the conical cap as follows:
V_cap = (1/3)π(10.5²)(9)
= 330.75π m³
Calculating the Volume of Air Trapped Inside:
To find the volume of air trapped inside, we need to subtract the volume of the conical cap from the volume of the cylinder.
V_trapped = V_cylinder - V_cap
= 1540π - 330.75π
= 1209.25π m³
Therefore, the volume of air trapped inside the given container is 1209.25π cubic meters.
