Well I would use the formula C=(1/4)pidiameter to get the distance traveled by the minute hand.
So it would look like C=(1/4)pi28
This would make the answer 7*pi or about 21.991 cm
Congratulations! YOU WON.
Great job :)
HELLO
ACCORDING TO MY MEASUREMENTS AND CALCULATIONS THE ANSWER SHOULD BE 20 CENTIMETERS.
Very close, but could be a bit better :) how did you do it?
did you say the minute hand has 14 cm. long
so i place the clock at 11:00 then i rotate the minute hand thru 11:15 and i took measurement from one point to another and my result was 20 cm.
so if a was wrong i hope someone can do it better.
thanks
ah I see it was close so i got curious :) it should be 22 if calculated!
Thanks!
14cm
Not quiet

Not quiet :) take another guess!
Will someone get the correct answer? :O

It is the question in text below, how long the minute marker moves in CM during 15 min, if the minute marker it self is 14 cm.
The answer is 21.98cm...which is approximately 22cm
The minute hand serve has a radius. It moves 11am to 11:15 which is 90degrees. Using radian×radius. A radian is 180degrees which is equivalent to a pie(3.14). But here it moved 90degrees, which is 3.14/2=1.57..so the distance covered is 1.57×14=21.98
Nice, you get second place, a bit late :)
Answer is 44cm
