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

How would you use the Fundamental Theorem of Calculus to determine the value(s) of b if the area under the graph g(x)=4x between

-BARSIC- [3]

The Fundamental Theorem of Calculus regarding geometry states that
$\int\limits^b_a g{(x)} \, dx = F(b)-F(a)$

Where F is the indefinite integral of $g(x)$

The first step is to integrate $g(x)$
$\int\ {4x} \, dx = \frac{4x^{1+1} }{1+1} = \frac{4x^{2} }{2} =2 x^{2}$

Then substitute the value of $b$ and $a=1$ into $2x^{2}$

$[2 (b)^{2}]-[2 (1)^{2}] = 240$
$2b^{2} -2=240$
$2b^{2}=240+2$
$2b^{2}=242$
$b^{2}= \frac{242}{2}$
$b^{2}=121$
$b=11$

Hence the limit of the area under $g(x)$ is between $a=1$ and $b=11$

A snowstorm dropped three and two-fifths inches of snow. The next day one and four-fifths inches melted, how much snow was left?

boyakko [2]

Answer:

After the melting there were one and three fifths of snow left.

Step-by-step explanation:

Given that a snowstorm dropped three and two-fifths inches of snow, and the next day one and four-fifths inches melted, the following calculation must be performed to determine how much snow was left:

2/5 = 0.40

4/5 = 0.80

3.40 - 1.80 = X

1.60 = X

0.60 = 3/5

Thus, after the melting there were one and three fifths of snow left.
