What is a diameter?</h3>
- A diameter of a circle is any straight line segment that passes through the center of the circle and has endpoints on the circle in geometry.
- It is also known as the circle's longest chord.
- Both definitions apply to the diameter of a sphere.
To find the distance hour hand travel in 5 hours:
- Let's say the hour hand completed one full round around the clock.
- If this was the case, it would have been 2
×8 inches around. - We know that the hour hand only traveled 5 hours around the clock rather than 12, thus our formula is 2
×8×( 5/12 ).
- Distance hour hand travel is 20.94 inches.
Therefore, the distance hour hand travel in 5 hours is 20.94 inches.

18 degrees F because
it dropped 12 degrees=10 hours
x degrees=15 hours
x is what you want to find out which is how many degrees it would drop in 15 hours.
12x15 then divided by 10 is 18.
