網頁Formula. The Circumference or Perimeter of a circle is: 2πR. Here, ‘r’ refers to the radius of the circle. Moreover, ‘π’ is the mathematical constant having an approximate value of about 3.14. Again, ‘π’ is a special mathematical constant here, it is the ratio in a circle, of circumference to diameter, where ‘C’ = ‘πD ... 網頁Let's begin with the formula for the area of a circle: π A r e a = π × r 2. From the formula, we see that we need the value of the radius. To find the circle's radius, we divide the diameter by 2, like so: r = 12 ÷ 2 = 6 m e t e r s. Now, we can input the radius value of 6 meters into the formula to solve for the area:

網頁We 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 ... 網頁Formula.
