Asked by Helen
The area of a circle can be calculated by the formula S=π ·r^2, where r is the
radius of the circle, or by the formula S=π ·d/4, where d is the diameter of
the circle. Write a formula expressing:
r in terms S
and d in terms of S

r = √(S / π)
d = √(4 S / π) = 2 √(S / π)
d = √(4 S / π) = 2 √(S / π)
