Question

he formula for the circumference of a circle is C = 2r, where r is the radius and C is the circumference. The equation solved for r is r = .

Find the radius of a circle that has a circumference of 16.

r = 4
r = 8
r = 12
r = 16

2 Answer

  • I think the answer is r=8..
    hope this helps!:)
  • Answer:

    Option 2nd is correct

    r = 8 units

    Step-by-step explanation:

    As per the statement:

    The formula for the circumference of a circle is C = 2r

    where, r is the radius of the circle

    To find the radius of the circle.

    Circumference(C)  = 16 units

    then;

    [tex]16 = 2r[/tex]

    Divide both sides by 2 we have;

    8 = r

    or

    r = 8 units

    Therefore, the radius of the circle is, 8 units
