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 × r 2. We transform it to the form r 2 = 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 ≈ ...

WebOct 23, 2011 · The equation for the circumference of a circle can be written in two ways: C = 2πr. C = πd. Where: r represents the radius of the circle, and d represents a circle's diameter. Recall that the radius is the distance from the center of the circle to a point on the edge of a circle, and the diameter is the largest distance across a circle.
WebFeb 17, 2024 · First we need to find the radius. The circle is 20 meters across, which is the diameter. The radius is half of that, so 10 meters. Now we just plug that into our formula: A = π r 2 A = π ( 10 m) 2 A = 100 π m 2 Finally, we multiply by on our calculator to get our approximate area: A ≈ 314 m 2 We need to buy a lot of sod! happy taxes in jefferson city tennesseeWebIf you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle. This is typically written as C = πd. happy tax seasonWebNov 28, 2024 · Finding the Radius or Diameter of a Circle Given Area.
