Whether you are finding the area of a circle or the area of a square or any other geometrical shape, it is always the case that to go from a linear measurement (a radius, a side, or whatever) to a surface area requires you to use a square of the linear measurement; you are increasing size in two dimensions, length and width, and therefore the effect is the increase the area exponentially, not linearly.

What is the algorithm for finding the area of a circle?
Find the radiusMultiply pi by the square of the radius.
Why do you square the radius when finding the area of a cirlce?
Because the circle is measured in square units.
Area of circle radius 2.5?
The formula for finding the area of a circle is A= pi r2. Square the radius then multiply it by pi. For your instance, 2.5 squared is 6.25. 6.25 x pi= 19.634... The area of a circle with the radius of 2.5 is 19.634...
What is a radius square?
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
Steps to finding the area of a circle?
1. Measure the radius and multiply it by itself (square it) 2. Multiply Pi (3.14159....) with answer of step 1. That will be the area. Area of circle = Pi x radius2 Radius = Half the diameter of the circle.
How do you find the radius of an inscribed circle of a square given the area of the circle?
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
How do you find the radius of an inscribed circle of a square given the area of the square?
Half the square root of the square radius equals the circle radius.
