Sagot :
Answer:
263.76cm
Step-by-step explanation:
r = 14cm
2πr = circumference = distance traveled in 1 hour
3(2πr) = 3x28xπ
π=3.14
= 84x3.14 = 263.76cm
HOPE THIS HELPS!!!
Answer:
2.6 m
Step-by-step explanation:
The minute hand on an oldfashioned (analog) clock will go completely around the clock 3 times in three hours.
The clock is a circle.
The length of the hand is the radius.
The distance around a circle is the circumference (it is perimeter for a circle!)
Circumference
= (pi)•d OR
= 2(pi)r
So the distance all the way around the clockface ONE TIME
is C = (pi)d = 2(pi)r =(3.14)28
= 87.96459 m
But in three hours it goes around three times.
3(87.96459)
= 263.89378
BUT this is cm and they asked for meters. So divide by 100, because there's 100 cm in a meter.
263.89378/100
~= 2.6 meters
