Answer:
9 cm
Step-by-step explanation:
Arc length = θ/360 × 2πr
A circle has an arc with a measure of 120 degrees and a lenght of 3π cm. What is the diameter of the circle
Hence,
3π = 120/360 × 2πr
Diameter = 2r
3π = 1/3 × 2πr
Cross Multiply
9π = 2πr
2r = 9π/π
Note that :
Diameter = 2r
Hence,
Diameter = 9 cm

Which proportion best compares age and tattoos?
The row data represents the age range of each group while the column data represents the amount of tattoo by each group.
So, to make comparison:
You simply pick a cell data and compare it to the row total.
<u>Take for instance</u>
For those who have at least 1 tattoo. The proportion to use are:
<em>170/490 --- For age range: 18 - 29</em>
<em>60/505 --- For age range: 30 - 29</em>
<em />
For those without tattoo. The proportion to use are:
<em>320/490 --- For age range: 18 - 29</em>
<em>445/505 --- For age range: 30 - 29</em>
