Question

Explain a method to find the thickness of a hollow tea cup.

Answer 1

In order to find the thickness of the teacup which is nothing but a hollow shaft, one needs to determine the inner and the outer radius of the cup.

The inner radius of the cup is the line from center to the inner walls of the cup and the outer radius is the line from center to the outer wall.

The difference of radius is the thickness of the cup

Answer 2

The thickness of a hollow tea cup can be calculated by subtracting its outer and inner radius.

Explanation:

The outer radius can be measured by calculating the distance from the center of the cup and the inner radius can be measured from the center of the cup to the inner circle.

In this way, the thickness of the hollow cup of the tea can be measured by making the difference between the outer and the inner radius.
