The formula for the volume of a wire is Δr2h, where r is the radius of the wire and h is the length. Find the volume of a wire if r = 0.518 units and h = 210 units Answers:
a)72,000 units^3
b)180 units^3
c)177 units^3
d)71800 units^3

9514 1404 393

  c)  177 units^3

Step-by-step explanation:

Put the given numbers into the formula in place of the corresponding variables, and do the arithmetic.

  V = πr²h

  V = π(0.518)²(210) = 56.34804π

  V ≈ 177.0 . . . units³

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
