If you divide the circumference C over the radius r, you get 2pi
2pi = C/r
this is because
C = 2pi*r
is one formula to find the circumference. Another formula is
C = pi*d
which works because d = 2r, ie the diameter is twice the radius.
When you want to round a number to the nearest hundredths
1.1<u>0</u><u />8
The 0 is in the hundredths place. So you look at the number to the right of the 0, is 8.
1.10<u>8</u>
If the number to the right is 5 or higher you round up, if it's under 5 you round down.
So 1.108 rounded to nearest hundredth is <u> </u>
<u>1.11</u>
Hope this helps. :)

Answer: The Circumference of a circle has the greatest measure.
Step-by-step explanation: A chord connects two points on a circle that are shorter than the diameter. The diameter is the measure across the widest part of the circle.
Circumference is the perimeter of the circle, the distance all the way around. It is π × diameter-- a bit more than 3 times the length of the diameter.
