Homework Statement
Calculate the pressure that an elephant with a mass of 4000 kg on the ground as the diameter of his legs is 25 cm
Homework Equations
P=F/A
F=mxg
The Attempt at a Solution
pressure = F/ A
diameter = 25 cm =>0.25m
I suppose his leg has form of circle so A = 3.14x (0.125)^2=0.049087
F=mass x g
F=4000kg x 9.81
F=39240 N
Thus,
P= 39240N / 0.049087 m^2 = 799390 Pa
But the answer should be 2.000x10^5 Pa
