Question

find the circumference. 11 in c =? in c = πd = 2πr use π = 3.14

Explanation:

Step1: Identify the radius

The radius $r = 11$ in.

Step2: Use the circumference formula

The formula for the circumference of a circle is $C = 2\pi r$. Substitute $r = 11$ in and $\pi=3.14$ into the formula. So $C=2\times3.14\times11$.

Step3: Calculate the result

$C = 2\times3.14\times11=69.08$ in.

Answer:

$69.08$ in
