Given:
The data values are 13, 6, 12, 9, 11, 14, 2, 8, 18, 16, 9, 12, 17, 11, 19, 6, 7, 12, 22, 21, 18, 1, 8, 12, 18.
To find:
The frequency distribution table for given data values by using the class intervals 0-5, 5-10,..., and draw a histogram.
Solution:
The frequency distribution table for given data values is:
Intervals Data values Frequency
0-5 2,1 2
5-10 6,9,8,9,6,7,8 7
10-15 13,12,11,14,12,11,12,12 8
15-20 18,16,17,19,18,18 6
20-25 22,21 2
To draw the histogram, intervals must be represented on the x-axis and frequencies represented on the y-axis as shown below:
Answer:
D
Step-by-step explanation:
The formula for volume of cone is
Where
V is the volume
r is the radius of the circular base
h is the height of the cone
<em>In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):</em>
