Question

The area of circle can be expressed by the formula A = πr2where r is a radius of circle. express radius in terms of area of circle.

Answer 1

Answer:

r=(A/π)^1/2

Step-by-step explanation:

A=πr^2.  When dividing π on both sides, you get r^2 = A/π. Meaning that r = the square root of A/π, or (A/π)^1/2
