Anumber has three digits. the number is less than 140.the number has 7 as a factor. the number is even. the sum of the digits is less than 9. what’s my number?

Step-by-step explanation:

Tough one!

Divisible by 7 and even...meaning it must be divisible by 14.

14 * x where x is less than 10 is the answer :)

That's the only thing I can figure out :)

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
