Given- 90% of runner completed the marathon.
out of which 30% are man.
To proof - let the total number of runner be y.
the men completed the marathon be 30% of the 90%.
thus we have
30% of 90% of y = 270
×
×y = 270
now solving the above equation
we get

Thus solving the equation
y = 1000
Thus the total runners of men who completed marathon be 1000.
Hence proved
Answer:
Step-by-step explanation:
Data sets are a collection of numbers related by a topic. The three ways to work with data sets include mean, median, and mode. The mean is the average of the data set, the median is the middle of the data set, and the mode is the number or value that occurs most often in the data set.
If we want to has 100 in the denominator we have to divide numerator and denominator by 2. Then total value of fraction doesnt change.

Now read the fraction, its 23 hundreds, now just write as decimal, so,
0.23
To find the volume of a cylinder you would multiply pi, radius squared, and height.
r= 6 ft
h= 2 ft
pi= 3.14
First you want to square your radius, so you would do 6 times 6.
This gives you 36.
Now you just multiply by 3.14 and get 113.04, then multiply that by 2.
Your final answer is 226.08ft³
