Answer:

Step-by-step explanation:

Multiply both sides of the equation by 2

2A = h sqrt(1-r)

Divide both sides of the equation by h

2A/h = sqrt(1-r)

Square both sides of the equation.

(2A/h)^2 = 1-r

Subtract 1 from both sides of the equation. Subtract 1 from both sides of the equation.

1 - (2A/h)^2 = r

r= 1- (2A/h)^2
