Answer:

Option 3 and Option 4

Answer:

D sqrt( A ) sqrt(pi) / pi = r

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

To find r

Divide each side of the equation by pi

A / pi = pi r^2 /pi

A / pi =  r^2

Take the square root of each side

sqrt(A / pi )= sqrt( r^2)

sqrt(A / pi )= r

We do not like leaving square roots in the denominator, so multiply by sqrt(pi)/sqrt(pi))

sqrt(A / pi ) *sqrt(pi)/sqrt(pi))

sqrt( A ) sqrt(pi) / pi = r
