The smaller triangle has a side of 16, while the corresponding side for the larger triangle is 64. 

The ratio of the two sides (small to large) is 16:64 which reduces to 1:4 after we divide both parts by 16. 

The ratio 1:4 basically means "multiply the smaller length by 4 to get the larger length". In other words, the larger length is 4 times longer. 

----------------------------------

From here, we square both parts of the ratio above
we go from 1:4 to 1:16 after we square both parts

What does the ratio 1:16 mean? It means that the larger area is 16 times that of the smaller area

If 
x = smaller area
y = larger area
then,
y = 16*x

----------------------------------

We're told that the larger area is 1360 square cm. So we know that y = 1360. Use this to find x

y = 16*x
1360 = 16*x
1360/16 = 16*x/16
85 = x
x = 85

----------------------------------

Answer: The smaller area is 85 square cm

To determine the lines that are parallel, you will need to find the missing angle length in the pairs of supplementary angles (totaling 180 degree).

180 - 114 = 66 degrees
180 - 112 = 68 degrees

Using these you can see the lines that are parallel.  They have matching angle measurements.

c // f
d // e

What is the exact volume of the cone?
zlopas [31]

Answer:

The third choice, (160/3)π cm³

Step-by-step explanation:

The formula for volume of a cone is

V = (1/3)πr²h   where r is the radius of the base, and h is the height

Here, r = 4 and h = 10. plug those values in and simplify...

V = (1/3)π(4²)(10)

V = (1/3)π(16)(10)

V = (1/3)π(160)

V = (160π)/3
