The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse.

Which is an equivalent equation solved for y?

a. y = a · πx
b. y = a + (πx)
c. y = a – πx
d. y = a ÷ (πx)

$$a = \pi xy $$
dividing both sides by pi x
$$\frac{ a }{ \pi x } = y$$
