Question

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

Answer 1

ANSWER :

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 :

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