Henry is conducting an experiment with 800 bacteria. he found the exponential growth rate to be 2.7% per hour. what is the amount of bacteria after 21 hours? round to the nearest whole number.
(hint: use the exponential growth formula : y= b(1+r)^t)

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

idk lol
