Find the area of the region that represents the solution of the inequality x^2+y^2 is less than or equal to 72. !

< indicates that the expression on the left is less than the expression on the right, for example:

indicates that 3 is less than 9 and we all know that to be true.

means that the solution to the expression on the left is less than zero, but more on that later.

> indicates that the expression on the left is greater than the expression on the right, for example:

shows that 9 is greater than 3 and similarly

means that the value of 2x - 9 is greater than 11

≤ indicates that the value on the left is less than or equal to the value on the right, for example:

means that the value of the expression on the left must be less than or equal to 25

≥ indicates that the value on the left is greater than or equal to the value on the right, for example:

Inequalities are best thought of as representing different regions on a number line:

< represents the region to the left of a given number, for example

Idon’t understand sorry
