Answer:the radius of a cone is the radius of its circular base. You can find a radius through its volume and height. Multiply the volume by 3. For example, the volume is 20.

Answer:

Either use the formula given below or , Use the formula for volume of a cone .

h = 36 \\Volume = 588pi\\r = \\588pi = \frac{1}{3}pir^{2} 36\\Cross-multiply\\1764pi=36pir^{2} \\Divide-both-sides-of-the-equation-by-36pi\\r^{2} =\frac{1764pi}{36pi} \\r^{2} = 49\\Square -root-both-sides-of-the-equation.\\\sqrt{r^{2} } =\sqrt{49} \\r = 7

Step-by-step explanation:

Volume -of -a- cone = \frac{1}{3} pir^{2} h\\Method 1 : Make- r- the -subject -of-the-formula.\\V = \frac{1}{3} pir^{2} h \\Cross-multiply\\3V = pir^{2} h \\Divide- both- sides -of- the -equation -by - pih\\\frac{3V}{pih} =r^{2} \\Square-root-both-sides-of-the-equation\\r = \sqrt{\frac{3V}{pih} }

Answer:

$1.22 per pair

The error is the contractor didnt take into account that there are 5 dozen gloves not 5 pairs of gloves. He calculated $73.20/5, which gave him $14.64.

Step-by-step explanation:

1 dozen = 12

5 dozen = 12 * 5 = 60

Therefore, you have 60 pairs of gloves.

He purchased all 60 pairs of gloves for $73.20.

73.20/60 = $1.22

This is how much one pair of gloves cost.

Suppose a problem said the stock is worth at least $14.50 how would I write and graph an inequality?
faltersainse [42]
X=the value of the stock
since it's at least $14.50, it could be more.
The inequality you'd write would be x \geq 14.50
To graph it on a number line, put a solid circle at 14.5 and shade the part to the right of it (since it's greater than 14.5).
To graph it on a coordinate plane, put a vertical line at x=14.5 and shade the part to the right of it.

Your Turn: Using the figure, a
Hatshy [7]
We are given:
\frac{a}{c} = \frac{d}{a}

First step is to get rid of fractions. We start by multiplying both sides by a.
\frac{a}{c} = \frac{d}{a} /*a \\

Now we cancel a on right side and we multiply both sides by c.
\frac{ a^{2}}{c} = \frac{da}{a} /*c \\ \frac{ a^{2}c}{c} = dc

After canceling c on the right side we are left with:
a^{2} = dc or a^{2} = cd

Dvinal [7]

Answer: 0.001

Step-by-step explanation:

Given

The lock has 3 dials, each with the number 0 through 9.

The first place can be filled in 10 ways and the probability of selecting number '4' out of the 10 is  \frac{1}{10}

Similarly for selecting '3' and '9' is also \frac{1}{10}

Therefore the probability of getting a combination of 4-3-9 is

\Rightarrow P=\dfrac{1}{10}\times \dfrac{1}{10}\times\dfrac{1}{10}\\\\\Rightarrow P=\dfrac{1}{1000}\\\\\Rightarrow P=0.001
