This is actually how people approximate real volume of obscured 3D objects.
volume of a traffic cone
approximate means about
Volume = pi*252*25 = 49087.38521 or about 50,000 cubic feet
Volume = 4/3*pi*143 = about 11494 cubic inches
The sphere's approximate volume is 523.6 cubic feet.
The approximate volume of a sphere with a diameter of 8 inches is 268 cubic inches.
inspiratory reserve volume= expiratory reserve volume + Tidal Volume - Vital capacity
2 miles cubed
You calculate the volume of three-dimensional figures, not of numbers like pi.
