Because they are parallel they have the same slope so m= 3
and then we can use the formula
(y-yo)=m (x-xo)
where 1 is xo and 3 is yo
after substitution
y-3=3x-3

y=3x+0

If the line is parallel, it will have the same slope but a different y intercept.
So, so far y=3x+b.
Because we know that this parallel line goes through (1,3), we can substitute these co-ordinates to get b:
3=(3 x 1)+b
3=3+b
0=b
So the equation of the parallel line is as follows:
y=3x+0

Answer:

1.5

Step-by-step explanation:

The scale factor can be found by dividing the side length from triangle ABC by the corresponding side length from triangle ABC

so the scale factor would be equal to

12/8 and 9/6

9/6 = 1.5

12/8 =1.5

so we can conclude that the scale factor is 1.5

Find the area of the top ( circle) then multiply by the height.

Area = pi x r^2

Area = pi x 7^2

Area = 49pi

Volume = 49pi x 15

Volume = 735pi cubic cm.
