Answer:

Part A) The volume of the entire cone is $168\pi\ in^3$

Part B) see the explanation

Step-by-step explanation:

Part A) we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of the cone

h is the height of the cone

In this problem triangle ABD is similar to triangle ACE

Remember that If two figures are similar, then the ratio of its corresponding sides is proportional

$\frac{AB}{AC}=\frac{BD}{CE}$

substitute the given values

$\frac{7}{14}=\frac{3}{x}$

solve for x

$x=14(3)/7\\x=6\ in$

To find out the volume of the entire cone we have

$r=CE=x=6\ in$

$h=AC=14\ in$

substitute in the formula

$V=\frac{1}{3}\pi (6)^{2}(14)$

$V=168\pi\ in^3$

Part B) How did you determine the value for x in triangle ACE

In this problem triangle ABD is similar to triangle ACE

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

$\frac{AB}{AC}=\frac{BD}{CE}$

substitute the given values and solve for x

Compare 3/5 and 6/9.

tiny-mole [99]

To compare you should make the down part equal first
27/45 < 30/45

The interior angles formed by the sides of a pentagon have measures that sum to 540°.

alexgriva [62]

Answer:

The Solution to the Sum

Your solution after multiplying the 3 with the 180 degrees is 540 degrees. This is true for any pentagon you have. Regular pentagons where all the sides and angles are the same will have a sum of interior angles of 540 degrees.
