Question

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

Answer 1

6.28

Step-by-step explanation:

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

Given data

Diameter d=
`2in`

Radius r =
`(d)/(2) = (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`
