Answer:
Yes it is correct
Step-by-step explanation:
So basically it makes a cone
one way to solve is
Vcone=(1/3)hpir^2
r=3
h=2
V=(1/3)(2)pi3^2
V=2pi3
V=6pi
aprox pi=3.141592
V=18.849
round
V=18.8 in^3
Answer:
(5x³+3x²-5x+4) + (8x³-5x²+8x+9)
= 5x³+3x²-5x+4 +8x³-5x²+8x+9
= 5x³+8x³+3x²-5x²-5x+8x+4+9
= 13x³-2x²+3x+13
Hope this helps
