y+y=2y
x×x=x²
therefore, y+y-x×x=2y-x²

Area=pi x r²r=6, hence Area =36pi

Radius = square root of 20
Centre = (3,2)

+6 or -6

In order to solve the question, we must find the value of y. First, we collect 'like terms'. This is when we put all the numbers on one side of the equals sign and put all the terms with y in it on the ot...
