Reason 1: Given
With any proof, the first line is always what you are given. You simply repeat it to set up a formal proof. Yes it seems redundant but it's just how proofs are done.

Reason 2: Vertical Angle Theorem
Vertical angles are formed by two lines crossing to form an X shape. The vertical angles are opposite one another. They are congruent angles.

Reason 3: ASA (angle side angle) Congruence Theorem
In statement 1, we found the A and S part, while statement 2 provides the other A allowing us to use ASA. Notice how the segment (S) is between the two angles (A)

Reason 4: CPCTC
Since we know the triangles are congruent (back in statement 3), we know the corresponding pieces are congruent. CPCTC stands for "corresponding parts of congruent triangles are congruent"

Debbie buys a tree for the holidays. She would like to determine the amount of space it will take up in her living room. The tre

Answer:

Volume of cone = 200.96 square feet

Step-by-step explanation:

We are given the following information in the question:

The tree is cone shaped and has a radius of 4 feet.

r = 4 feet

The height of the tree is three times its radius.

$h = 3\times r = 3\times 4 = 12\text{ feet}$

Volume of tree =

$\text{Volume of cone} = \displaystyle\frac{1}{3}\pi r^2 h$

Putting all the values, we get,

$\text{Volume of tree} = \displaystyle\frac{1}{3}\pi (4)^2 (12)\\\\= \frac{1}{3}\times 3.14\times 4\times 4\times 12 = 200.96\text{ square feet}$

Radius of cone whose height is is equal to three times its radius is given as:

$V = \displaystyle\frac{1}{3}\pi r^2 h\\\\V = \displaystyle\frac{1}{3}\pi r^2 (3r)\\\\3V = 3\pi r^3\\\\ r = \sqrt[3]{\frac{3V}{3\pi}}$
