Question

the minute hand of a circular clock is 11 cm long how far does the tip of the minute hand move in 2 hours? (take π =3.14)

Answer 1

Answer:

Step-by-step explanation:

2*2Pie*R

4*3.14*11

= 138.16 cm

Answer 2

Answer:

Step-by-step explanation:

• we can say that  radius of the clock=11 cm
• each hour difference angle is 360/12=30 degrees
• so  for 2 hours the angle is 60 degrees
• area of sector=theta/360 .pi.r^2=60/360 into 3.14 into 11 into 11
• area of the sector=63.32cm^2
• so it moves 63.32cm^2
