Area of Circle with Radius
Area = πr2
where,
r is the radius and π is the constant value
Example: If the length of the radius of a circle is 3 units. Calculate its area.
Solution:
We know that radius r = 3 units
So by using the formula: Area = πr2
r = 3, π = 3.14
Area = 3.14 × 3 × 3 = 28.26
Therefore, the area of the circle is 28.26 units2
Area of a Circle: Formula, Derivation, Examples
Area of a Circle is the measure of the two-dimensional space enclosed by a circle. It is mostly calculated by the size of the circle’s radius.
