Radius equation using circumference
WebGiven, Radius of the circle = 28 cm. To find the circumference of the circle, we will use the circumference formula: 2πr = 2 × 22/7 × 28 = 176 cm. Therefore, the circumference of the circle is 176 cms. Example 2: The circumference of a …

WebJan 26, 2024 · Radius to circumference formula. If you are given the radius, r, you can still find the circumference. If you know the radius, the circumference formula is: C=2\pi r C = 2πr. You can always find the … 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.
WebAug 2, 2024 · The radius is the distance from the center of the circle to its edge. [1] Example If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. 2 If you know the circumference of the circle, divide it by π to get the diameter. π is equal to approximately 3.14 WebNov 7, 2024 · Use the formula C/2π. Since the circumference is equal to πD, which is equal to 2πr, dividing the circumference by 2π will give the radius. If you have a sphere with a circumference of 20 m, find the radius by dividing 20/2π = 3.183 m. Use the same formula to convert between the radius and circumference of a circle.
WebFirst you need to know that the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 where the center is at point (a,b) and the radius is r. so for instance (x-2)^2 + (y-3)^2 = 4 would have the center at (2,3) and have a radius of 2 since 4 = 2^2. This means if you went a distance of 2 away from that center point you would be on the circle. WebJan 8, 2024 · Calculate the arc length according to the formula above: L = r * θ = 15 * π/4 = 11.78 cm. Calculate the area of a sector: A = r² * θ / 2 = 15² * π/4 / 2 = 88.36 cm². You can also use the arc length calculator to find the …

WebDiameter: the largest distance between any two points on a circle; by this definition, the diameter of the circle will always pass through the center of the circle. It is equal to twice the length of the radius. Circumference: the distance around the circle, or the length of a circuit along the circle. Arc: part of the circumference of a circle bodies and twists hnos brownWebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps!
