To find the metal area of given washer.
Answer to Problem 56A
Area of given washer is
Given information:
A washer is given as below indicating dimensions in millimeter.
Calculation:
As we know that area of a circle is given by -
Here, radius length of the smaller circle is
So, area of the smaller circle will be -
Similarly, radius of the larger circle is
So, area of the larger circle will be -
Now, area of the washer is area of smaller circle subtracted from area of larger circle. i.e.
Area of washer
