scoray [572]

Answer:

6.28

Step-by-step explanation:

This problem bother on the mensuration of flat shapes, a circle.

Volume v =

Diameter d= $2inches$

Radius r = $=\frac{diameter}{2} = \frac{2}{2} = 1 in$

Since we are required to solve for the circumference of a circle

The expression for the circumference of a circle is given as

$C= 2\pi r$

$C= 2*3.142*1\\C= 6.28$

The question insist that we type just a number hence the circumference $6.28$ of the plug is 6.28
