What is the solution of the system of inequalities

There are four (4) whole-number solutions to these inequalities:

... {(4, 1), (5, 0), (6, 0), (7, 0)}

Step-by-step explanation:

These are nicely solved by graphing. Whole numbers are non-negative integers, so x and y can be any values 0, 1, 2, .... The area of overlap on the graph clearly shows that y=0 and y=1 are the only viable choices for y, and that the values for x are limited in each of these cases.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
