A 80-kg person sits on a 2.7kg chair. Each leg of the chair makes contact with the floor on a circle that is 1.3 cm in diameter. Find the pressure exerted on the floor by each leg of the chair, assuming that the weight is evenly distributed.

Explanation:

Area = (πr²)

        = 1.33 m²

Pressure = Force/Area

               = 827/1.33

               = 621.8 Pa
