WebCircumference of a circle = 2πr. Formula 2: When the diameter of a circle is known. Circumference = πd. Formula 3: When the area of a circle is known, we can write the formula to find the perimeter of the circle as: C = √ (4πA) Here, C = Circumference of the circle. A = Area of the circle. WebFeb 2, 2024 · Method #2 – Diameter from Circumference Calculator. Formula – How to calculate the diameter of a circle from the circumference ... Formula – How to calculate the diameter of a circle using the radius. π is approximately 3.1415926535. Diameter = Radius x 2. Example. A circle has a radius of 10. Diameter = 10 x 2 = 20. WebWe know that the radius of a circle is always perpendicular to the chord of a circle and it acts as a perpendicular bisector. Therefore, AD = 1/2 × AB = 16/2 = 8. Therefore, AD = 8 cm. Example 2: In the given circle, O is the center with a radius of 5 inches. Find the length of the chord AB if the length of the perpendicular drawn from the ... grandmother in haitian creole
