Surface Area = 4*PI*r^2
r = SQRT(SA/4/PI)

sphere
surface area = 4pi times( r squared)
so
r squared= area/ 4pi
r = square root of (area/4pi)

a=4*pi*(r^2)
and r = sqrt(a/4pi)

4(pi)r^2 or r = sqrt[1/4(pi)]

S = 4pi * r^2
r^2 = S/(4pi)
r = sqrt(S/(4pi))
r = (sqrt(S))/(sqrt(4pi))
r = (sqrt(4pi * S))/(4pi)
r = (2sqrt(pi * S))/(4pi)
r = (sqrt(pi * S))/(2pi)
