Question

what is radius formula?????​

Answer 1

circumference

$\frac{circumference}{\pi} = radius$

Answer 2

Given,

What is radius formula,

• Radius: Then the line segment made will be the radius of the ring.
• We can easily derive at the radius by dividing the diameter of the circle by $2$.
• Radius $= \frac{diameter}{2}$
• We can also compute the radius if we know the length of the circumference of the circle or area of the circle.
• Thus a unique circle will have a unique value of radius.
• Radius $=\frac{Circumference}{2\pi }$.
