A circle has a circumference of x feet and an area of y square feet. If x=2y, what is the radius of the circle
2 answers:
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
-
Answer: r = 1
x=2y is linear and can also be writtend as y=x/2
