Question

the hose is 2 inches in diameter. What circumference does the plug need to be? remember to type just a number

Answer 1

Answer:

6.28

Explanation:

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

Given data

Diameter d= $2in$

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

We know that the expression for the circumference of a circle is given as

$C= 2\pi r$

Substituting our given data and solving for C we have

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