I think the volume of the sphere is 4 centimeters.
The time would be 9:10 am because 4 + 4 = 8 and then 25 + 45 is 70 so an hour is 60 minutes and then you just add the extra 10 minutes
3yds because 1 yards is 3 feet so 3 times 3=9 feet greater than 8feet
Can you search it as a pdf and some answers should pop of hope this helps
