Volume of cylinder =Π r^2 h
where 'r' refers to radius and 'h' refers to height of the cylinder
volume of cylinder = Π (2)^2 (6)
= Π (4)(6)
=Π (24)
75.36 cm^3 is the volume of the cylinder.
Slope intercept form is y=mx+b
m(slope)=1/2
(x,y)—->(-8,-4) so x=-8 and y=-4 substitute and solve for b
-4=1/2(-8)+b
-4=-4+b
+4=+4
0=b
