Answer:
0.96cm
Explanation:
Given parameters:
Weight of person = 645N
Pressure of the heel = 9000000PA
Unknown
Diameter of the circular base = ?
Solution
Pressure is the force per unit area of a body.
Pressure =
To solve this problem, find the unknown area of the circle;
Pressure x Area = Force
Area =
Area = = 7.17 x 10⁻⁵m²
Note: 1Pa = 1Nm⁻²
Now;
Area of a circle = π r²
r =
Area = π x
d is the diameter
d² = 4 x Area x (1/π)
d² = 4 x 7.17 x 10⁻⁵ x (1/3.14) = 9.13 x 10⁻⁵
d = 0.0096m
To cm;
100cm = 1m
0.0096m; 0.0096 x 100= 0.96cm
