To solve for y, all you have to do is just separate r from all of the others and make it equal to the rest of the equation. So first it was, a=pi*r squared.
Divide by pi on each side,
a/pi=r^2
Take the square root of each side;
square root of (a/pi) =r
and that's all
Hope this helps.

use the formula V*t=x so if the velocity is 8 2/3 miles per hour and you need to travel 5 1/5 miles then (8 2/3)*t=5 1/5,
so t=(5 1/5)/(8 2/3)= .6 hours
