The area of a circle is modeled by the equation A = πr^2. Rewrite the equation in terms of the circles radius r. In your final answer, include all of your calculations. (brainliest to best answer)

Sagot :

Answer:

First off, the area of a circle should be pi times r squared, not r times pi squared. I will do my math using this correction.

If A = (pi)r^2 then first we can devide both sides by pi, leaving

A/pi = r^2

 To solve for r, we need to take the square root of both sides, leaving

sqrt(A/pi) = r

or

r = sqrt(A/pi)

Step-by-step explanation:

this would be your answer

r = √(A/π)

Step-by-step explanation:

A = πr²

A/π = r²

±√(A/π) = r

But the only thing is that you can't have a negative radius, so you just have to  rewrite  the answer as positive.

√(A/π) = r
