Hey mate ,
In this particular question we have to find the volume of given objects and compare to find which has the greatest volume.
Lets Solve ,
Volume of cone :- 1/3πr²h
putting the known values ,
Volume = 1/3×3.14×5²×7 cubic ft.
Volume :- 183.1 cubic ft.
Volume of Sphere = 4/3πr³
putting the known values ,
Volume = 4/3×3.14×5³ cubic ft.
Volume = 523.33 cubic ft.
Volume of Cylinder = πr²h
putting the known values ,
Volume = 3.14×5²×7 cubic ft.
Volume = 549.5 cubic ft.
Volume of hemisphere = 2/3πr³
Putting the known values ,
Volume = 2/3×3.14×5³ cubic ft
Volume = 261.66 cubic ft.
Comparing the volume of each object , we can find that the Cylinder has the greatest volume
