The two numbers differ by about 9 orders of magnitude, so the value of the difference between the larger and the smaller is essentially the value of the larger number. The smaller one, by comparison, can be considered to be zero (for subtraction purposes).
The area of the circle is approximately 50
<h3>Areas</h3>
The area of a shape is the amount of space occupied by the shape
<h3>Area of circle</h3>
Given the three radius of the circle, the area of the triangle is calculated using:
From the figure, we have:
--- the radius
So, we have:
Approximate
Hence, the area of the circle is approximately 50
