The formula for calculating the area of a circle is: Area = π * r²Where "Area" is the circle's area.(pi) is a Mathematical constant with an approximate value of 3.14159. r is the radius of the circle, which is the distance squared (raised to the power of 2) from the circle'...
This circle has an area ofapproximately 14 But using a formula (when possible) is best: Example: The circle has a radius of 2.1 meters: The formula is: Area =π× r2 Where: π= thenumber pi(3.1416...) r = radius The radius is2.1m, so: ...
The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The distance from the center point to any endpoint on the circle is called the radius of a circle. Learn about the radius formulas with solved examples
