Answer:

Formula for Radius

The formulas to find the radius are quite simple. If you know the diameter of the circle, use this formula:

If you don't know the diameter, but you know the circumference, you can use this equation:

If you know the area of the circle, use this equation:

Note that the area of a circle is essentially the total space, measured in square units, inside of the perimeter of a circle.

Answer 2

Answer:

Step-by-step explanation:

We can find the radius of the circle using two ways...    1.if the diameter of the circle is given, then the radius will always be half of it

ex :If the diameter is 14cm,then the radius is1/2 of 14=7cm

2.If the diameter is not given and the circumference is given then

we use the formula of 2*pi*r

to find radius

we equate radius to one side and then use it to find .

hope it is clear....
