Question

Length of minute hand is 7cm and length of hour hand is 4 cm. Find (a) Distance covered by both hands in 4 days. (b) Area swept by both hands in 2 hours.​

Answer 1

PLS MARK ME BRAINLIEST

circumference = 2× pie×r

for minutes hand

=2×22×7

7

=44

Distance covered=circumference × no.of. rounds

= 44×96

= 4,224 cm

for hours hand

= 2×22×4

7

=25.142

=25.14

Answer 2

Step-by-step explanation:

a). To find the distance covered by both of the hands we need to find their circumfarence÷

circumference of min. hand

=2πr

=2*22/7*7

=44cm

circumference of the second hand

=2πr

=2*22/7*4

=37.714

distance covered = 44+37.714=81.714cm

distance covered in 4 days=81.714*4=326.856

b.) distance covered in 2 hours=326.856*1/22

=14.857
