The answer would be 0.13658537...
but when you estimate it the answer would be 0.14
In terms of diameter (d), the area (A) of a circle is given by the formula
A = (π/4)d²
You have d=20 yd, so the area of the circle is
A = (π/4)×(20 yd)² . . . . substitute the given information into the formula
A = 100π yd² . . . . . . . . do the arithmetic
A ≈ 314.16 yd²

Answer:
The correct option is b.
Step-by-step explanation:
Standard deviation is one of the measure of dispersion or spread of a dataset from the average value of the dataset. The standard deviation measures the absolute variability of the distribution of values.
The higher the spread or variability in the data set, the greater is the standard deviation value and thus greater will be the magnitude of the deviance of the value from their average.
It is provided that the standard deviation of the distribution of house age is about 16 years.
The standard deviation of 16 years imply that the age for all the houses in the sample is 16 years from the mean.
Thus, the correct option is b.
Y= 70°
In an isosceles triangle the two base angles are the same and as angles in a triangle add to 180, 180-40=140, 140/2= 70
