    Answer:

    21 meters

    Step-by-step explanation:

    circumference of a circle is πd, or π2r

    so, to find the radius, we simply must divide the circumference by everything used to find is BESIDES the radius, in order to single it out

    42π / 2π   =   21

    the radius is 21 meters
