Find the approximate value of the circumference of a circle with the given radius. use pi = 3.14. round your results to one more decimal than in the given radius.
4.6 inches

28.89 inches

Step-by-step explanation:

The circumference of a circle is given by :-

, where r is the radius .

Given : The radius of a circle = 4.6 inches

Then the circumference of the circle will be :-

Therefore , the circumference of the circle = 28.89 inches

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
