Question

he 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?

y = a · πx
y = a + (πx)
y = a – πx
y = a ÷ (πx)

Answer 1

Start with a = π x y. Divide both sides by πx to isolate y:

y = a / (πx).

So the correct choice is: y = a ÷ (πx).
