Understand that you can easily determine the area of a circle using the formula Area = π × r^2, where π is approximately 3.14, and r represents the radius of the circle.
The formula for the area of a circle is A = πr 2, where r is the radius of the circle. The unit of area is the square unit, for example, m 2, cm 2, in 2, etc. The area of a circle formula is useful for measuring the region occupied by a circular field or a plot.
How to Calculate the Area. The area of a circle is: π ( Pi) times the Radius squared: A = π r2. or, when you know the Diameter: A = (π/4) × D2. or, when you know the Circumference: A = C2 / 4π. Example: What is the area of a circle with radius of 3 m ? Radius = r = 3. Area = π r2. = π × 32. = 3.14159... × (3 × 3) = 28.27 m2 (to 2 decimal places)
Area of a circle is equal to the product of pi and r-squared. Area of circle is region enclosed by it. Visit BYJU'S to learn the area of circle formula, definition, derivation, along with solved examples.
Area of a circle – formula and examples. The area of a circle can be thought of as the number of square units of space the circle occupies. This can be found using either the radius or the diameter, which we will cover in the examples below.
Since a circle is 2 – dimensional, its surface area is the same as its area. The area of a circle may be calculated when the length of its radius, diameter, or circumference is known.
