Answer:

C = 14 pi inches

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

49 pi = pi r^2

Divide each side by pi

49 pi/pi = pi /pi r^2

49 = r^2

Take the square root of each side

7 = r

The circumference is given by

C = 2 * pi *r

C = 2 * pi *7

C = 14 pi inches

Which of the following is the main of the set of data below? 30, 29, 28, 30, 24, 12, 26, 33, 25, 23

Marianna [84]

Answer:

The mean of the data is 26.

Step-by-step explanation:

Consider the provided data:

30, 29, 28, 30, 24, 12, 26, 33, 25, 23

Mean can be calculated as:

The average of all the data in a set.

$x=\frac{\Sigma x_{i}}{n}$

Therefore,

$x=\frac{30+29+28+30+24+12+26+33+25+23}{10}$

$x=\frac{260}{10}$

$x=26$

Thus, the mean of the data is 26.
