Solve like an algebraic equation
C= 2(3.14)r
remove ( )
C- 6.28r
divide by 6.28
C/6.28=r
hope this helps
3 terms. Abcd is one term
E is another term. -h27 is the third term
It would be 100. Because let's say you had to round 25 to the nearest 10 it would be 30 because everything ending with 5 (example: 5 to nearest 10 would go to 10 65 to the nearest ten would go to 70) but anything lower then 5 goes to the lower number.
You are moving in the path of a parabola.
The conic section is parabolic - the street is the directrix and the mailbox is the focus.
The answer to 3 x 10 is 30. Think of it as 3 groups of 10. Each of the 3 groups has 10.
