Find the median and mode of the following data: a) 5, 9, 3, 4, 9, 2, 1, 3, 6.
b) 60, 67, 62, 61, 63, 65, 64, 68, 60.

A is 4 and b is 63 have a good day

A) To find the median list the numbers in ascending order. (1, 2, 3, 3, 4, 5, 6, 9, 9) The middle number is the median. So the answer is 4.
The mode is the number that appears the most which is 3 and 9 because they both appear twice.
B) (60, 60, 61, 62, 63, 64, 65, 67, 68) The middle number is 63 so that is the median.
The mode is 60 as it appears the most in the list.
Pls give me the brainliest!

C = 14 sqrt(pi)

Step-by-step explanation:

The formula for area of a circle is

A = pi r^2

49 = pi r^2

Divide each side by pi

49/pi = r^2

Take the square root of each side

sqrt(49/pi) = sqrt(r^2)

sqrt(49/pi) = r

Now we need to find the circumference

C = pi * 2 *r

C = pi * 2 * sqrt(49/pi)

C = pi * 2 *7/sqrt(pi)

We need to get rid of the qrt(pi) in the denominator) so multiply by sqrt(pi)/sqrt(pi)

C = pi * 2 *7/sqrt(pi) * sqrt(pi)/sqrt(pi)

C 14 pi* sqrt(pi)/pi

The pi in the numerator and denominator cancel

C = 14 sqrt(pi)
