You have to think about where the numbers are vs where the decimal point is.
Also, saying the number out loud helps.
Two hundred six and forty seven thousandths
Two hundred (200) plus six (6) and then you need to keep the decimal where it is and put the other two together.
So the answer is 200 +6 +.04 +.007
Did you get it?
Hope this helped!!(:

Hello!
I do believe you meant to say:
"What is the difference between a <em>ray</em> and a line segment?"
The difference between a ray and a line segment is:
A ray has one endpoint and continues in one direction. a ray is infinite
A line segment has two endpoints. a line segment is finite
I hope this helps, and have a nice day!
<h3>Problem Solution</h3>
Assuming the spool is a cylinder and the circumference we're winding around is that of a circle with the given area, we can write the relation between circumference and area as
... C = 2√(πA)
10 times the circumference is then
... 10C = 20√(π·20 cm²) = 40√(5π) cm ≈ 159 cm
<h3>Formula Derivation</h3>
The usual formulas for circumference and area are
... C = 2πr
... A = πr²
If we multiply the area formula by π and take the square root, we get
... πA = (πr)²
... √(πA) = πr
Multiplying this by 2 gives circumference.
... C = 2√(πA) = 2πr
