WebFeb 2, 2024 · The circle perimeter formula is: p = 2πr, where p is the circle's perimeter, r is the radius, and π is a constant equal to approximately 3.14159265... You can also express the perimeter in terms of the diameter ( d ), remembering that r=d/2: p = πd. 💡 The number π is a constant equal to the ratio of the circumference to the diameter (or ... WebFor example, the circumference of a circle with a radius of 4 inches is simply 2 x 3.14159 x 4 = 25.13 inches. If the diameter is given instead, first divide it by two, then repeat the above process. For example, if the …

WebA circle of radius = 12 or diameter = 24 or circumference = 75.4 feet has an area of: Use the this circle area calculator below to find the area of a circle given its diameter, or other parameters. To calculate the area, you just need to enter a positive numeric value in one of the 3 fields of the calculator. WebThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. commonwealth scholarships uk
