Answer:

3375 $\pi \\$ 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.

Determine the recursive function that defines the sequence.

<h2>Answer:</h2>

Option: C is the correct answer.

C. $f(1)=4\\\\f(n)=5\cdot f(n-1)\ ;\ n\geq 2$

<h2>Step-by-step explanation:</h2>

Recursive Formula--

It is the formula which is used to represent the nth term of a sequence in terms of (n-1)th term of the sequence.

Here we are given a table of values by:

n f(n)

1 4

2 20

3 100

i.e. when n=1 we have:

$f(1)=4$

Also,

$f(2)=20\\\\i.e.\\\\f(2)=5\cdot 4\\\\i.e.\\\\f(2)=5\cdot f(1)$

Also,

$f(3)=100\\\\i.e.\\\\f(3)=5\cdot 20\\\\i.e.\\\\f(3)=5\cdot f(2)$

Hence, the recursive formula is:

$f(n)=5\cdot f(n-1)\ for\ n\geq 2$
