The answer should be about 13 as the sequence over 5 number is increasing by 20 so over each interval it should increase by 4.
The equation for a cone is
V=(1/3)hpir^2
if pi=aprox 3.14 for this quesiton
and r=6 and h=13
V=(1/3)(13)(3.14)(6^2)
V=(1/3)(13)(3.14)(36)
V=(13)(3.14)(12)
V=(3.14)(156)
V=489.84 cubic units
Hi there!
To find our answer we need to collect the terms of the expression.

The coefficient (which is the number just before the variable) of the simplified expression is 13.
2(x+5)2+8x+5+6=0 is the answer
Answer:
x^3 <-- exponent, x to the power of three
Explanation:
x(x+2)(x+4)
=(x(x+2))(x+4)
=(x(x+2))(x)+(x(x+2))(4)
=x^3+2x^2+4x^2+8x
=x^3+6x^2+8x
