Circumference related to diameter
WebDec 14, 2024 · Determine the radius of a circle. Let's assume it's equal to 14 cm. Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm. You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm². Finally, … Pi is the most well-known mathematical constant. It's a ratio of a circle's … WebSep 29, 2024 · There are two formulas that can be used to calculate the circumference of a circle: C = 2πr or C = πd, where π is the mathematical constant approximately equal to 3.14, [4] r is equal to the radius, and d is equal to the diameter. [5] Because the radius of a circle is equal to twice its diameter, these equations are essentially the same.

WebIn this case, the slope of the trendline is the ratio of the change in circumference to the change in diameter. The slope of the trendline is calculated by dividing the change in circumference (22.0 - 18.3) by the change in diameter (7.7 - 5.3), giving a slope of 1. WebFeb 2, 2024 · Use the formulas to calculate the circumference and area: c = 2πr and A = πr². The circumference should equal c = 2π × 8 cm = 50.265 cm. The area should equal A = π × (8 cm)² = 201.06 cm². To check your results, input the 8 cm diameter in the calculator. The results should also be 50.265 cm and 201.06 cm².

WebFeb 2, 2024 · To find the radius whose circumference is equal to 6 feet, we follow the steps below: Write the circumference as c = 6 ft. Recall the formula for the radius of a circle from circumference: r = c / (2 * π). Inject the circumference into the equation: r = (6 ft) / (2 * π) = 3/π ft. If needed, substitute π ≈ 3.14: r = 3/π ft ≈ 0.96 ft.
