Question

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? o y = a·πx o y = a+(πx) o y = a - πx o y = a÷(πx)

Explanation:

Step1: Isolate y in the formula

Given $a = \pi xy$, divide both sides by $\pi x$.
$\frac{a}{\pi x}=\frac{\pi xy}{\pi x}$

Answer:

D. $y = a\div(\pi x)$
