Which number is the additive inverse of -4 1/4

Step-by-step explanation:

We are given that a number

We have to find the number which is additive inverse of  given number.

Additive inverse: That number which is equal and opposite to given number and when added to given number then their sum will be zero.

To find the additive inverse of given number we will convert given number inti simple farction .

The number is equal to given number and opposite to given number and sum of and is equal to zero.

Hence, the additive inverse of given number is

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
