Andrea totaled the distance she ran on Monday, Tuesday, and Wednesday. Her sum is 14.225. A 2-column table with 3 rows titled To
tal distance Andrea Ran (kilometers). Column 1 has entries Monday, Tuesday, Wednesday. Column 2 has entries 3.6, 4.705, 5.92. Rounding to the nearest whole kilometer, determine whether Andrea’s sum is reasonable. Round Monday’s distance to . Round Tuesday’s distance to . Round Wednesday’s distance to . Was Andrea’s sum reasonable?
c = circumference
pi = 3.14
r = radius = 9 inches
d = diameter
c=pi*d
The radius is half of the diameter, d = 2r. Then d = 2*9=18.
plug into equation. c= pi*d = 3.14*18
round accordingly and you may want to include that the measurement you end up with is in inches.
