6 gru 2023 · How to calculate the area of a circle. In this article we show you how to derive the famous equation for the area of a circle. Most students simply memorize the formula and plug in numbers in order to calculuate the area of a circle.
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)
Solution. Given: d i a m e t e r , d = 5 u n i t s. We have to find the Area of Circle using given diameter. Formula: We know that the formula to find the Area of Circle is. A r e a , A = π π d 2 4. Substitution: Substitute the given values in the above formula. A = π π d 2 4. A = 3.1415 × 5 2 4. A = 19.6344 square units. Result:
