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. WebFeb 17, 2016 · In order to calculate a circle’s circumference, we need to know either its diameter or its radius. We then use the appropriate value in this equation: C = 2 π r (where “ r ” represents radius, of course). Ex. Find the circumference of this circle: r = 10 units 2 = 5 units C = 2 π r = 2 π × 5 = 10 π units Q Why is circumference 2 π r? A

How to Find the Circumference and Area of a Circle: 14 Steps - WikiHow
WebTo find the radius from the diameter, you only have to divide by two: r=d/2 r = d/2. If you know the circumference it is a bit harder, but not too bad: r=c/2\pi r = c/2π. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area, on the other hand, is all the space contained inside the circle. 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. WebJan 16, 2024 · How to find radius from circumference.
