What is the volume of a cone with diameter 21 m and height 4 m?

natima [27]

For this case we have by definition, that the volume of a cone is given by:

$V = \frac {1} {3} * \pi * r ^ 2 * h$

Where:

A: It is the cone radius

h: It's the height

They tell us that the diameter is 21 m, then the radius is half the diameter, that is: 10.5m. The height is 4m. Substituting the data:

$V = \frac {1} {3} * \pi * (10.5) ^ 2 * 4\\V = \frac {1} {3} * \pi * 110.25 * 4\\V = 147 \pi$ .

Finally, the volume of the cube is $147 \pi \ m ^ 3$

The table show the age in years of employees in a company

adelina 88 [10]

Answer:

A. 24 ≤ a < 26.

B. 22.5

Step-by-step explanation:

A. Determination of the modal class interval.

Mode is the class with the highest frequency.

From the table given above, the highest frequency is 8, therefore the class will the highest frequency is:

24 ≤ a < 26.

B. To obtain the mean, we must determine the class mark. This is illustrated below:

Class >>>>> class mark >>> frequency

18 – 19 >>>> 18.5 >>>>>>>>> 3

20 – 21 >>> 20.5 >>>>>>>> 2

22 – 23 >>> 22.5 >>>>>>>> 7

24 – 25 >>> 24.5 >>>>>>>> 8

26 >>>>>>>> 26 >>>>>>>>> 0

The mean is given by the summation of the product of the class mark and frequency divided by the total frequency. This is illustrated below:

Mean = [(18.5x3) + (20.5x2) + (22.5x7) + (24.5x8) + (26x0)] / (3+2+7+8+0)

Mean = (55.5 + 41 + 157.5 + 196 + 0)/20

Mean = 450/20

Mean = 22.5

Therefore, the mean age is 22.5

The shaded part of the diagram shows what tina had left from a yard of fabric.she now use 1/3 yard yard of fabric for one projec

ioda

Answer: Left over yard after the two projects is $\frac{1}{2}\ yards$

Step-by-step explanation:

Since we have given that

Number of yard of fabric for one project is given by

$\frac{1}{3}$

Number of yard of fabric for second project is given by

$\frac{1}{6}$

Total number of yards of first and second project is given by

$\frac{1}{3}+\frac{1}{6}\\\\=\frac{2+1}{6}\\\\=\frac{3}{6}\\\\=\frac{1}{2}\ yards$

Number of original of fabric Tina have left after the two project is given by

$1-\frac{1}{2}\\\\=\frac{2-1}{2}\\\\=\frac{1}{2}\ yards$

Hence, Left over yard after the two projects is $\frac{1}{2}\ yards$
