Circles!! 50 pts
Find 10 circular objects that you can measure. Think outside the box (or should I say think outside the circle). Car tire, lid to a jar etc.
Fill in the chart below and see if you can determine a relationship within any of the columns. If you do not have a flexible tape measure then use a string or
piece of yarn to find the distance around and then measure the yarn with a ruler.
Object
Circumference
Use tape measure or yarn
to measure. If you use
yarn, be sure to measure
the length of the yarn
afterwards using a ruler or
yardstick
Diameter Radius Area
C/D
(circumference divided by
the diameter)
Round to the nearest 4th
decimal place
Look at each column carefully. Did you find any patterns? What conclusion can you draw from your exploration above?

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

Isec i will do it and them i will let you know
