The radius of a circle measures 16 mm what is the circumference of the circle?
use 3.14 for a way to get an answer do not round the answer

100.48mm

_____________

The formula for calculating the circumference of a circle is 2πr or 2 * pi * radius.

You are given that the radius is 16mm. You are also told to use 3.14 as a way to solve the problem. If you were going to use π, it cannot be displayed as a number without rounding. Looking at it's value, 3.1415.... We can reasonably assume that they want us to use 3.14 instead of pi. Now let's calculate it:

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
