If we take both sides of the equation 
and <em>multiply either expression by 3</em>, the equality becomes
Multiplication of both sides of an equality by the same number keeps the equality true, and we call this property the multiplication property of equality.
Answer:
A = 
. r^2
If A = 9ft^2
. r^2 = 9ft^2
r^2 = 9ft^2
r = sqrt(9ft^2)
r = 3ft ( r>0)
