Answer : The correct option is, (C) 226ft^3

Step-by-step explanation :

As we know that tree trunk is in cylindrical shape. So, we are applying volume of cylinder to calculate the volume of tree trunk.

Formula used :

V=\pi r^2h

where,

V = volume of tree trunk

r = radius of tree trunk = 3 feet]

h = height or length of tree trunk = 8 foot

Now put all the given values in the above formula, we get:

V=\pi r^2h

V=3.14\times (3)^2\times 8

V=226ft^3

Therefore, the volume of tree trunk is, 226ft^3

Explain how to find the range of a data set. What is an advantage of using the range as a measure of​ variation? What is a​ disa
Eduardwww [97]

Answer:

1) The range is found by subtracting the minimum data entry from the maximum data entry.

2)  It is easy to compute.

3)  It uses only two entries from the data set.    

Step-by-step explanation:

We are given the following information in the question:

1) Range is difference between the highest value and the lowest value of the data.

  • To find the range we first arrange the data in the increasing order and then select the highest and the lowest value of the data, Then the lowest value is subtracted from the highest value to find the range.

Option A) The range is found by subtracting the minimum data entry from the maximum data entry.

2) Advantage of range as a measure of variation.

  • Since the method to calculate range of a data set is very easy, it is one of the advantages to use range as a method of variation.

Option B)  It is easy to compute.

3) Disadvantage of range to use as a method of variation.

  • The disadvantage of using range is that it does not measure the spread of the data set
  • It only measures the spread between highest and lowest data points in data set.

Option C) It uses only two entries from the data set.

the length of a rectangle is 3cm more than the width. find the length and the width if the perimeter of the rectangle is 98cm.
laila [671]

The perimeter of a rectangle is <u>length + length + width + width</u>.

We know that the length of a rectangle is 3cm more than its width, which gives us the equation:  (l for length and w for width)

l = 3 + w

We also know that the perimeter of the rectangle is 98cm, which gives us the equation:

98 = 2l + 2w         (equation for perimeter of a rectangle as noted above)

We can divide both sides of this equation by 2 to get:

49 = l + w

Now we'll stick l = 3 + w into the above equation, which gives us:

49 = 3 + w + w

which simplifies to 49 = 3 + 2w.

Now we'll subtract 3 from both sides:

49 - 3 = 46

3 + 2w - 3 = 2w

which gives us 46 = 2w.

Dividing both sides by 2 gives us 23 = w.

Substituting w = 23 into the equation l = 3 + w gives us:

l = 3 + 23

l = 26cm.

Let's check our answer.  26cm is 3cm more than 23cm.  26cm + 26cm + 23cm + 23cm gives us 98cm.  The length is 26cm and the width is 23cm.
