treat the tree trunk as a cylinder
v= pi x r^2 x h
using 3.14 for pi
3.14 x 3^2 x 10 = 282.6 cubic feet
282.6 * 45 = 12, 717 pounds
Answer:
-5x+22
Step-by-step explanation:
we are simplifying
2x-(-8)-7x+4+10=
2x+8+-7+4+10=
2x+8+-7x+4+10
(2x+-7)+(8+4+10)= -5x+22
Hope it helps

Answer: 
<u>Step-by-step explanation:</u>
The formula for factoring a cubic is:
a³ + b³ = (a + b)(a² - ab + b²)
f(x) = x³ + 3³
= (x + 3)(x² - 3x + 9)
To find the zeros, set each factor equal to zero and solve.
0 = x + 3 0 = x² - 3x + 9
-3 = x use quadratic formula
