WebFeb 28, 2024 · In terms of mathematical formulas, the circumference of a circle is the outcome of the constant π and the diameter/radius of the circle. Circumference of circle= C = 2 π r Here π is the constant which is equal to 22 7 or 3.14159. R = Circumference 2 π or C 2 π units Radius using Area of Circle WebMay 11, 2024 · The Circumference of a circle goes with this formula; C = 2πr. Where'; C = Circumference. π = 22 7 or 3.142. r = radius. Hence you can find the radius of the circle from the circumference.. C = 2πr. Divide both sides by 2π.
WebWhen the diameter of a circle is known, the formula is, Radius = Diameter/ 2. For example, if the diameter is given as 24 units, then the radius is 24/2 = 12 units. When the …
WebAug 2, 2024 · 3. If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter. This goes back to manipulating the formula for finding the area of a circle, A = πr 2, to get the diameter. You can transform this into r = √ (A/π) cm.
