Question

Giakhanh · Answer

The  circumference  of the wire is 4x and the  area  of the circle is 4x^2/π    How to determine the circumference?  The  length  of the wire is given as;  Length = 4x    This represents the  circumference .  Hence, the  circumference  of the wire is 4x    How to determine the area?  In (a), we have:  Circumference = 4x    Calculate the radius using:  2πr = 4x    Divide through by 2π  r = 2x/π    The area is:  Area = πr^2    This gives  Area = π(2x/π)^2    Evaluate  Area = 4x^2/π    Hence, the  area  of the circle is 4x^2/π    Read more about  circumference  at:  https://brainly.com/question/14283575    #SPJ1
