Answer:
k = 4
Step-by-step explanation:
Step 1: Write equation
-3k - 9 = -21
Step 2: Solve for <em>k</em>
- Add 9 to both sides: -3k = -12
- Divide both sides by -3: k = 4
Step 3: Check
<em>Plug in k to verify it's a solution.</em>
-3(4) - 9 = -21
-12 - 9 = -21
-21 = -21
20✔️3 + 4✔️27
20✔️3 + 4✔️9 • 3
20✔️3 + 4 • 3 ✔️3
20✔️3 + 12✔️3
32✔️3.
The solution is 32✔️3.

Answer:
3375 
cubic centimeters
Step-by-step explanation:
Trick question: The largest piece is the entire cone.
First lets identify the equation for volume.
V= 1/3 h pi r^2
h=45
r=15
V= 1/3 45 * pi 15^2
v= 15* pi 225
3375 pi
You keep pi because the answer has pi.
