A candle manufacturer sells cylindrical candles in sets of three. Each candle in the set is a different size. The smallest candl

dem82 [27]

Answer:

A. 27 π cubic inches

Step-by-step explanation:

The volume of a cylinder is calculated using the formula;

$Volume=\pi r^2h$

From the given information, the smallest candle has a radius of 0.5 inches and a height of 3 inches.

We substitute $r=0.5$ and $h=3$ into the given formula.

The vlume of the smallest candle is

$Volume=\pi \times0.5^2\times 3$

$Volume=\frac{3}{4}\pi in^3$

from the given information, the other two candles are scaled versions of the smallest, with scale factors of 2 and 3.

The volume of the other two candles will be $2^3\times \frac{3}{4}\pi=6\pi in^3$ and $3^3\times \frac{3}{4}\pi=\frac{81}{4}\pi in^3$

The wax needed to create one set of candle is

$\frac{3}{4}\pi+6\pi+\frac{81}{4}\pi=27\pi\: in^3$

The correct answer is A

A population of rabbits doubles evey 4 months. if the population starts out with 8 rabbits how many rabbits will there be in 1 y

Airida [17]

If it doubles in every 4 months, then in 1 year it will double by 12/4 = 3 times.

So, the expression would be: n³
n = number of rabbit at starting point = 8

So, after 1 year, it would be = 8³ = 512

So, your final answer is 512

Hope this helps!
