WebJan 3, 2024 · Here, the value of π is approximately 3.14 (which is slightly greater than three) and D is the diameter of the circle. While calculating the circumference of the circle, π is being multiplied with the diameter, and π is slightly greater than 3. That's why, we can say that the circumference is greater than thrice of the diameter. [(π × D ... Web5 years ago. You just need to use the equation. First, find the equation for the circle. Like this, x^2 + (y - 3)^2 = 9. Then, input the x and y values into the equation. If it's bigger than 9, the point is outside of the circle, if it's equal to 9, the point is on the circle, and if it's smaller than 9, the point is inside of the circle.

WebYou can choose which way you express the circumference of a circle. The reason that most people use 2πr as the formula is because the radius of a circle or a face of a circular object is used more often than the diameter. For example, the area of a circle is πr^2. This is much easier than writing π(d/2)^2. WebExample 1: If the radius of a circle is 7 units, then the circumference of the circle will be. 2 × π × 7 = 2 × 3.14159 × 7. = 43.98 units. Example 2: Suppose that the diameter of the circle is 12 feet. Then, we can use the formula πd to calculate the circumference. Circumference = πd = 3.14159 × 12 = 37.69 feet.
