Area of Circle in terms of Diameter
The diameter of a circle is double the length of the radius of the circle, i.e. 2r.
The area of the circle can also be found using its diameter
Area = (π/4) × d2
where,
d is the diameter of the circle.
Example: If the length of the diameter of a circle is 8 units. Calculate its area.
Solution:
We know that diameter = 8 units
so by using the formulas: Area = (π/4) × d2
d = 8, π = 3.14
Area = (3.14 /4) × 8 × 8
= 50.24 unit 2Thus, the area of the circle is 50.24 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.
Let’s learn how to find the area of the circle using the formulas, with the help of examples.
