How to find the volume of the cone

Answers

Answer:

The closest measurement to the volume of hat is 84.82 in.³.

Step-by-step explanation:

Given:

The dimensions of hat are height(h) 9 inches and diameter(d) 6 inches.

Now, to find the volume of cone:

Putting the formula $(1)/(3)\pi r^(2)h$ .

Radius(r) is not given, finding the radius:

Radius(r)=half of the diameter(d)

$r=(d)/(2)$

$r=(6)/(2)$

$r=3$ .

Then, $(1)/(3)\pi r^(2)h$

= $(1)/(3)*\pi *3^(2)*9$

= $(1)/(3)*3.14*9*9$ ( $\pi =3.14$ )

= $(1)/(3) *254.34$

= $(254.34)/(3)$

= $84.78$ in.³

So, the volume is 84.78 in.³ .

Therefore, the closest measurement to the volume of hat is 84.82 in.³.

What is the producr of 5 and 1/8

Answers

There are two easy ways.
The way I was taught:
1. Make 1/8 a decimal by dividing 1 by 8 (Numerator by denominator.), leaving you with 5*.125=.625, or 5/8.
The ACTUAL easy way:
2. Make 5 a fraction by putting it over 1, giving you 5/1*1/8, leaving you with 5/8.

The answer is 5/8 of course

a geologist had two rocks on a scale that weighed 2 1/2 pounds together rock A weighed a total of 1/7 of the weight how much did rock A weigh

Answers

Answer:

Let A and B be the two rocks.

As per the statement: a geologist had two rocks on a scale that weighed 2 1/2 pounds together rock

⇒Total weight of rock ( $A+B$ ) = $2(1)/(2)$ pounds

$A+B= (5)/(2)$

Also, it is given A weighed a total of $(1)/(7)$ of the weight.

⇒ $A = (1)/(7) * (\text{Total weight})$

then;

$A = (1)/(7) * (5)/(2) = (5)/(14)$

Therefore, $(5)/(14)$ pounds did rock A weight.

It is already given in the question that the combined weight of two rocks is 2 /1/2 pounds. The weight of rock A is also known and it is 1/7 of the total weight of the two rocks. This is enough to find the desired solution.
Now
Total weight of the two rocks = 2 1/2 pounds
   = 5/2 pounds
Then
Weight of Rock A = (5/2)/(1/7) pounds
   = (5 * 7)/2 pounds
   = 35/2 pounds
   17 1/2 pounds
So Rock A weighs 17 1/2 pounds. This is the weight of Rock A and it is only required for this question. If you are eager to find the weight of rock B then you have to subtract the weight of Rock A form the total weight of the two rocks.

on a toy assembly line, 3% of the toys are found to be defective. The quality control officer predicts that 872 toys will be found defective out of the 24,850 toys made. Do you agree with this prediction? Explain.

Answers

No, I don't agree with this prediction.
If you were to times 24,850 by 3% you would get 745, which would be the number of defective toys.
872 defective toys is 3.5% of 24,850 toys.
