Determine the value of pie for a circle with a diameter of 9 inches and a circumference of 28.26 inches

Hello from MrBillDoesMath!

3.14

Discussion:

C = circumference, r = radius, d = diameter = 2 r

For a circle, C = 2 Pi r  = d Pi

Substituting the values in the question gives

C = d Pi

28.26 = 9 Pi       => divide both sides by 9

Pi = 28.26/9  = 3.14

Thank you,

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
