Answer:
The answer is 117.3 .
Step-by-step explanation:
To solve for the volume of the cone, use the cone volume formula, which is V = .
Next, plug in the information given from the problem, and the formula will look like V = .
Then, solve the equation, and the answer will be 117.3 .
Answer:
Step-by-step explanation:
Hello, please consider the following.
So this is divisible by 3.
Now, to prove that this is divisible by 9 = 3*3 we need to prove that
is divisible by 3. We will prove it by induction.
Step 1 - for n = 1
4+17=21= 3*7 this is true
Step 2 - we assume this is true for k so is divisible by 3
and we check what happens for k+1
is divisible by 3 and
is divisible by 3, by induction hypothesis
So, the sum is divisible by 3.
Step 3 - Conclusion
We just prove that is divisible by 3 for all positive integers n.
Thanks
