Method 1 Using Radius to Find Area Download Article 1 Identify the radius of a circle. The radius is the length from the center of a circle to the edge of the circle. You can measure this in any direction and the radius will be the same. The radius is also one half of the diameter 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)

How Do You Find The Area Of A Circle With Just The RadiusExample 2. Find the area of the circle. Answer: Step 1: Identify the radius. Remember, the radius is the distance from the center to the outside - halfway across the circle. The 10 marks the diameter, not the radius. To find the radius, we need to take half of 10. r = 5. Step 2: Plug 5 into the formula. Step 3: Simplify.
