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
x = -1/2
The mean of the data is 26.
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.
Therefore,
Thus, the mean of the data is 26.
6 2/3 meters per second
800 meters in 2 minutes
Change the minutes to seconds
We know 1 minutes =60 seconds so 2 minutes is 120 seconds
Take the 800 meters and divide by 120 seconds
800/120 =6.66666666 meters per second
