First, find the mean. You'll need it to compute the variance.
The variance of the sample is then computed with the formula
The standard deviation is the square root of the variance, so
Let the number of men and the number of women in the beginning be x and y
Now,
Now, In 2nd case,
No. Of men=x-63 and no. Of women =y-12
Now,the ratio becomes
Now,we have, 2x=5y
Putting the value of Y=56 in 2x=5y,we get,
Hence, the number of men was 140 and the no. of women was 56

Answer:
D. 12²•π
Step-by-step explanation:
Area of a circle = πr²
Radius (r) = ½ of diameter = ½*24 = 12 inches
Plug in the value into the area
Area = π * (12)²
Area = π * 12²
Area = 12²•π
