Find the Circumference in the example below using the steps provided. Use 3.14 for Pi. Do not round. Be sure to label your answer.

where is the example

I can't answer the question without the example provided, but here are some steps to solve it.

Basic info-

Circumference (C)

3.14 is used for pi π= 3.14

The line halfway of the circle is the radius(r)

The line through the circle is the diameter(d)

Formulas:

C= 2πr

2 × 3.14 × the radius

OR

C= πd

3.14 × the diameter

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
