Answer:

The answer to your question is:

12) C

13) AT = 29

Step-by-step explanation:

12)

Data

A (6, -3)

B (-6, 19)

midx = (x1 + x2) / 2 midy = (y1 ´y2) / 2

midx = ( 6 - 6) / 2 midy = (-3 + 19) / 2

midx = 0 / 2 midy = 16 / 2

midx = 0 midy = 8

mid point = (0, 8)

13)

As A is the midpoint of CT then CA = AT

2x - 19 = x + 5

2x - x = 19 + 5

x = 24

AT = 24 + 5

AT = 29

Use cavalieri's principle to a circular pillar candle is 2.8 inches wide & 6 inches tall. find the volume of the candle.

wolverine [178]

The candle has the shape of a cylinder with height H=6 in, and radius of the circular base R= (2.8)/2 =1.4 (in).

The volume of the cylinder is Area(base)*height =

$\pi R^{2} *H=3.14* (1.4)^{2}*6= 37$ (in cubed)

According to Cavalieri's principle, the volume of the candle is equal to the volume of the cylinder we described.

Answer: 37 in cubed
