Question

Rewrite the formula for area of a circle to find the radius of a circle.
The area of a circle (A) is given by the formula where r is the circle's radius. The formula to find r is . If and , r is centimeters.

Answer 1

Answer:

r=√ {A/$\pi$}

Step-by-step explanation:

Area of a circle is given by = $\pi$ r²

A=$\pi$ r²

Making r the subject of the fomula

r² = A/$\pi$

eliminating the square

r=√ {A/$\pi$}
