If h = 11 units and r = 4 units, then what is the approximate volume of the cone shown above?

Volume of a cone formula:

V = PI x r^2 x h/3

Replace r and h with the given information and solve:

V = PI x 4^2 x 11/3

V = 3.14 x 16 x 11/3

V = 50.24 x 11/3

V = 184.21 cubic units.

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
