The pressure she exerts on the carpet sample:-5.8279 MPa
P = F/A
Where,
F= Force
A = Area
Given that;
d= 0.987 cm =0.987 Â x 10^-2 m
m= 45.5 kg
Area = πr^2= (π(0.987  x 10^-2)^2/2)
    =7.6511 x 10^-5  square meter
Force= mg
    = 45.5 x 9.8
    =445.9 N
Pressure = force/ area
       =445.9/7.6511 x 10^-5
       =5.8279 MPa
The pressure she exerts on the carpet sample:-5.8279 MPa
