Distance travelled by the minute hand in 30 minutes

= (1/2) of the circumference of the circle of radius 14 cm

= {(1/2)×2×(22/7)×14}cm

= 44 cm

$\large \bold \red{NotE-}$ In a circle, Minute hand is equals to its radius.

Answer 2

Answer:-Distance covered = 44 cm

Displacement = 28 cm

Explanation = Length of minute hand of clock = 14 cm

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circle

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clock

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R=\frac{22}{7}\times 14=722×14

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R=\frac{22}{7}\times 14=722×14=44=44 cm

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R=\frac{22}{7}\times 14=722×14=44=44 cmFrom 10 AM to 10:30 AM, the displacement of the tip of the minute hand will be twice the length of the minute hand

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R=\frac{22}{7}\times 14=722×14=44=44 cmFrom 10 AM to 10:30 AM, the displacement of the tip of the minute hand will be twice the length of the minute handHence, displacement

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R=\frac{22}{7}\times 14=722×14=44=44 cmFrom 10 AM to 10:30 AM, the displacement of the tip of the minute hand will be twice the length of the minute handHence, displacement=2R=2R

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R=\frac{22}{7}\times 14=722×14=44=44 cmFrom 10 AM to 10:30 AM, the displacement of the tip of the minute hand will be twice the length of the minute handHence, displacement=2R=2R=2\times 14=2×14

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R=\frac{22}{7}\times 14=722×14=44=44 cmFrom 10 AM to 10:30 AM, the displacement of the tip of the minute hand will be twice the length of the minute handHence, displacement=2R=2R=2\times 14=2×14=28=28 cm

Length of minute hand of clock = 14 cmFrom 10 AM to 10:30 AM, the minute hand will complete one half circleThe radius R of this circle will be the length of the minute clockTherefore, the distance covered=\pi\times R=π×R=\frac{22}{7}\times 14=722×14=44=44 cmFrom 10 AM to 10:30 AM, the displacement of the tip of the minute hand will be twice the length of the minute handHence, displacement=2R=2R=2\times 14=2×14=28=28 cmHope this answer is helpful.
