Circumference of a 3' diameter circle
WebFeb 9, 2024 · If you know the diameter of the circle: r = d / 2 If diameter and area are unknown: r = c / 2π If diameter and circumference are unknown: r = √ (a / π) How to find the center of a circle? There are many ways to find the center of a circle. Here we'll show you two constructional methods: 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.
