Answer:
39 in or 3'3"
Step-by-step explanation:
The radius is just half the diameter, so convert into inches first, then divided by 2. And convert back if you need to.
Since it’s in percents, put the percent over 100 as a fraction and simplify them. For percents that aren’t given, add the rest and subtract it from 100 and then place it as a fraction over 100
Turn into military time
1:22 turns into 13:22
5:44 turns into 17:44
Then you subtract 13:22 from 17:44
You will get the answer
5hrs and 22mins
Finally convert hrs into mins and add all the mins together
You’ll get
322 mins
As your answer
