Distribute and add like terms
-(6a³-3a+8)=-6a³+3a-8

now add
3a²+4a-6-6a³+3a-8
regroup
-6a³+3a²+4a+3a-6-8
-6a³+3a²+7a-14
dat is expanded and compacted

Data:
r (radius) = 14 m
h (height) = 6 m
v (volume) = ?

Formula:
$V = \pi *r^2*h$

Solving:
$V = \pi *r^2*h$
$V = \pi *14^2*6$
$V = \pi *196*6$
$\boxed{\boxed{V = 1176 \pi\:m^3}}\end{array}}\qquad\quad\checkmark$
