\text {Circumference = } 2 \pi r

c = 2 \pi r

\text {r = }  \dfrac{c}{2 \pi }


\text {area = }  \pi r^2

Sub r into area:

\text {area = } \pi ( \dfrac{c}{2 \pi } )^2

\text {area = }  \dfrac{\pi c^2}{4 \pi^2 }

\text {area = }  \dfrac{\ c^2}{4 \pi }

A doctoral student wants to determine the relationship between steps per minute and the time it takes to walk 100 feet in
Rina8888 [55]

Using correlation coefficients, it is found that that the correct option is given as follows:

The correlation would stay the same because the change in units for time would have no effect on it.

<h3>What is a correlation coefficient?</h3>
  • It is an index that measures correlation between two variables, assuming values between -1 and 1.
  • If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
  • If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

The correlation coefficient does not have units, hence if the units of the measures is changed, the coefficient remains constant, which means that the correct option is given by:

The correlation would stay the same because the change in units for time would have no effect on it.
