The formula for the circumference is 2πr.
The diameter d is given, which is 2 times the radius r (d = 2r)
So you have to calculate π d = 3.142×1.8 ≈ 5.7

You can use bar graphs to compare quantities in real life situations by comparing different amounts, ex. you might use them for comparing different prices at a coffee shops around the world or different types of dogs you see at a park on a sunny day. You can really use bar graphs for comparing anything.
Hello,
Since √25 = 5 and √36=6, it is known that √35 lies between 5 and 6. And then you drag the mouse to approximately 5.9 since √35 ≈ 5.9
Good Luck
The measure of each exterior angle = the measure of each central angle.
each angle = 360 / 16 = 22.5
