Conna wants to track the rate of growth of a seedling. which answer is appropriate for describing the rate in this context? milliliters per minutegrams per secondmiles per hourmillimeters per week < < ? (just to make sure if my answer is correct)

millimeters per week

Step-by-step explanation:

Given: Conna wants to track the rate of growth of a seedling.

From the given options millimeters per minute is not the appropriate unit for describing the rate of growth of a seedling because seedling will not grow few millimeters in a minute.

Also grams per second is not the appropriate unit for describing the rate of growth of a seedling because 'grams' unit is used to describe the weight not length.

Also miles per hour is not the appropriate unit for describing the rate of growth of a seedling because 'miles' unit is used to describe the distance traveled.

Thus, millimeters per week is the only option which is appropriate for describing the rate in this context.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
