Acircle has a circumference of x feet and an area of y square feet. if x=2y, what is the radius of the circle

x=2y is linear and can also be writtend as y=x/2

Formula: circumference = 2πr

Formula: Area = πr²

-

Given circumference = x and area = y and x = 2y

-

2πr = 2πr²

Divide by 2πr on both sides:

r = 1

-

r = 1
