What is the difference between the circumference of the outer circle and the circumference of the inner circle? Leave your answer in terms of π.

Diameter is 9m and the outer part of the circle is 2m

Will give brainiest

22\pi m

Step-by-step explanation:

Given:

Diameter is 9 m and the outer part of the circle is 2 m

To find: difference between the circumference of the outer circle and the circumference of the inner circle

Solution:

Diameter of inner circle = 9 m

Radius of the inner circle (r)  

Circumference of the inner circle

As outer part of the circle is 2 m,

outer radius (R) = r + 2 = 4.5 + 2 = 6.5 m

Circumference of the outer circle

So,

difference between the circumference of the outer circle and the circumference of the inner circle m

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
