Find the volume of the cone. Round to the nearest hundredths.

The volume is 134.04 in^3

Step-by-step explanation:

V= πr^2h/3

v= 3.14 * 4^2 * 8 /3

v= 3.14 * 16 * 8 /3

v= 134.04

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
