Answer:
1 and 19/36 inches
Step-by-step explanation:
All you have to do is subtract the woman's height by her son's height.
59 and 1/12 - 57 and 5/9 is 1 19/36
Find thy radius.
Thy radius is 7.25 (D / 2 = R)
Thy formula for area is A = (pi)r^2
Substitute and Solve
A = (pi)r^2
= (pi)(7.25)^2
= (pi)(52.5625)
= 165.04625
Therefore, the area is about 165.
The answer is 3.4, you need to subtract 1.6 from 5.

The area of the semicircle
First, we calculate the hypotenuse (h) of the triangle
Considering only the triangle, we have:
--- cosine formula
Make h the subject



The area of the semicircle is then calculated as:

This gives:
