How do you find circumference using radius

C=π×2r

Circumference is equal to pi times double the radius

   Determine the radius of a circle. Let's assume it's equal to 14 cm.

   Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm.

   You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm².

   Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm.

   Use our circumference calculator to find the radius when you only have the circumference or area of a circle.

If you wish to calculate the properties of a three-dimensional solid, such as a sphere, cylinder or cone, it's best to use our volume calculator.

         Hope this helped a little :)

over the argument its not good to fight.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
