Where 'V' is the volume of a cone, 'r' is the radius, and is π = 3.14.
When measured, the radius (r) of the circle is 5", and the height (h) is 10".
V = 1/3 x π x 5² x 10
V = 1/3 x π x (5 x 5) x 10
V = 1/3 x π x 25 x 10
V = 1/3 x π x 250
V = 1/3 x 785
V = 261.67
The volume of cone is 261.67 cubic inches.
