I got a but I'm not sure.
A.132ft
B.264ft
C.1,320FT
D.2,640FT

    What is the diameter?

  • math -

    not sure. All I got was a line with 42 ft with a dot in the middle

  • math -

    That's probably the diameter. Let's see if it works.

    C = pi * d
    C = 3.14 * 42
    C = 131.88

    Thar rounds to 132 feet. You're right.
