2. Write as an exponential expression : -X•-X•-X

X^3

x^3

Step-by-step explanation:

6 * 6 * 6 = 6^3

banana * banana * banana = banana^3

x * x * x = x^3

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

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
