Question

The minute hand of a Cicular clock is 15 cm long. How far does the tip of the minute hand move in (b) 30 minutes ? (Take π = 3.14)

Answer 1

Answer:

94.2 cm

Step-by-step explanation:

in 30 minutes hand will complete half rotation

so it can be considered a semi circle

distance will be arc length or simply we can take it as half the perimeter since angle is 180 after half rotation

d=2*pi*r

=2*3-24*15

=30*3.14

=3*31.4

d=94.2 cm
