Tell me if the number are rational or irrational
ill send you a request and you
the square root of 25
the square root of 225
the square root of 78
the square rot of 59
in advance

   = 5     (perfect square ⇒ rational)
 = 15   (perfect square ⇒ rational)
   = 8.831760866      (irrational)
   = 7.681145748      (irrational)

A rational number can be expressed in the way a : b or 
An irrational number cannot be expressed this way!

Step-by-step explanation:

The general equation of a circle has the form:

Where r is the radius of the circumference.

In this problem we have the circle with equation

1) The intercepts with the x-axis we find them doing y = 0 and solving for x:

The intercepts with the y-axis we find them doing x = 0 and solving for y:

The 4 interceptions are:

2) The radius is:

3) The area of a circumference is:
