Question

Need to find circumference of the circle. Use 3.14 for the value of pi. m let diameter = 20 in

Answer 1

the circumference of the circle is 62.8 inches

Explanation

the circumference of a circle is given by:

$\text{Circumference(C)}=\text{ Diameter(D)}\cdot\pi$

Step 1

Let

$\begin{gathered} \pi=3.14 \\ \text{Diameter}=\text{ 20 in} \end{gathered}$

now, replace in the formula

$\begin{gathered} \text{Circumference(C)}=\text{ Diameter(D)}\cdot\pi \\ C=\text{ 20in }\cdot3.14 \\ C=62.8\text{ inches} \end{gathered}$

therefore, the circumference of the circle is 62.8 inches
