## 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
