Question

How do you work out the radius of a circle from its area ?

Answer 1

Area of circle:

A = pi(r)^2

to solve for r radius, first divide both sides by pi:
A/pi = r^2

then sq root both sides:
sq root(A/pi) = r

so if you were given the area of a circle, divide the area by pi then find the square root to find the radius

Answer 2

Answer:

u divide the area by 3.14

Step-by-step explanation:

it reverses the area
