We have the equation xy-7y=49.
First, we factor out the common term for "y"
y(x - 7) = 49
Now, divide both sides by x - 7.
y = 49/x-7 <====

Since the area formula is pi times radius to the second power, then just plug in the things you know. for ex: The area is 314, then work backwards and divide 314 by pi which equals 100 then unsquare it which is 10 because 10*10=100. So the radius is 10
