Answer:
Step-by-step explanation:
Given:
The area 'A' of a circle with radius equal to 'r' is given as:
In order to rewrite the given formula in terms of radius 'r', we need to isolate 'r'.
Dividing both sides by π, we get:
As 
, the above equation becomes:
Taking square root both the sides, we get:
We neglect the negative result while taking square root as the radius can't be a negative number.
Thus, the formula for radius 'r' in terms of area 'A' is given as:
Answer:
equal to
