Answer 2

The radius is always half of the diameter. So divide 11 by 2.

Answer 3

\[11\div2\]

Answer 4

the circumference of a circle is equal to 2 * pi * r
pi is a constant those value is 3.1415926535898. if the radius is 11 inches, then the circumference is equal to 2 * pi * 11 = 2 * 3.1415926535898 * 11 = 69.1150383789756.
you can also leave the answer in terms of pi.
in that case, the circumference is equal to 2 * pi * 11 = 22 * pi.

Answer 5

Once you divide those two numbers, you get the radius.
