Question

Find the circumference of each circle. Use ( pie symbol) as 22/7 Number 10. 1 1/3

Answer 1

The circumference is 88/21 inches or 4.19 inches

EXPLANATION :

From the problem, we have a circle with a diameter of 1 1/3 in.

Note that the circumference of a circle is :

`C=2\pi r\quad or\quad C=\pi D`

Since we have a diameter, we will use the second formula :

The circumference will be :

`\begin{gathered} C=((22)/(7))(1(1)/(3)) \\ C=((22)/(7))((4)/(3)) \\ C=(88)/(21)\quad or\quad4.19 \end{gathered}`
