WebJan 16, 2024 · The radius to circumference formula is: C=2\pi r C = 2πr Radius of circle from area You can use the area to find the radius and the radius to find the area of a circle. The area of a circle is the space it occupies, measured in square units. Given the area, A, of a circle, its radius is the square root of the area divided by pi: WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different … If you know the circumference (say 20pi), you can find the radius, because every …

WebWe get; Example 1: The circumference of a wheel is 308 cm. Find the radius of the wheel. Therefore, the radius of the wheel is 49.01 cm. Example 2: Suppose the circumference of a bicycle wheel is 30 cm and you are asked to find the length of each of the spokes. The bicycle spokes originate from the center of the wheel to its circumference. WebApr 6, 2024 · The radius is approximately equal to 1.785. The precise answer is √ (10 / π). To get this result, recall the formula area = π × r2. We transform it to the form r2 = area / π, and so we see that the radius is equal to the square root of area / π. Plugging in area = 10, we obtain: radius = √ (10 / π) ≈ √ (10 / 3.14) ≈ √3.185 ≈ 1.785. chin up bar free standing
