A gardener has a flower pot that he wants to fill with dirt. The flower pot has a radius of 8 cm at its opening and a radius of 7 cm at its base. The flower pot has a height of 10 cm. Part A:
Provide an estimate for the amount of dirt, in cubic centimeters, that the gardener will need to completely fill the flower pot.
Part B:
Explain how you determined your answer.

 B will show different time from the other.

Step-by-step explanation:

Since we have given that

Skateboarder     Time ( in seconds)

 A                              4.28

 B                              4.24

 C                              4.26

 D                              4.25

Now, we round off to the nearest tenth of a second,

Time taken by A = 4.28 = 4.3 seconds

Time taken by B = 4.24 = 4.2 seconds

Time taken by C = 4.26 = 4.3 seconds

Time taken by D = 4.25 = 4.3 seconds

So, if the stopwatch can measure to the nearest tenth of a second,  

'B' skateboarder will show as having a different time from the other.

Hence, B will show different time from the other.
