A. 28.26 sq in
Explanation:
The formula for the area of a circle is πr^2.
r represents the radius. Since the radius is 3, we can plug it in to find the answer.
π3^2
9π
9(3.14) = 28.26

when you apply a number greater than 1 to the x value, it compresses the x value by the denominator of the fraction.
Answer:
Variability
Step-by-step explanation:
Variability in simple terms may be described as differences in measurement or reading of a certain construct or phenomenon. Variability measures include range, standard deviation or variance. In most cases, variation or degree of Variability is measured about a central value called the mean. This is because same measurement about a certain phenomenon or study would usually not yield the same result value. Hence, the mean is used to record the average of these measurement and the differences in each measurement from the mean is also recorded, this is called the standard deviation which is a Variability measure.
Thus VARIABILITY means successive observation of a phenomenon do not yield exactly the same result.
Amount after 11 years = 5000(1 + 0.11)^3 = $6838.16
so interest is 1638.16 dollars
