$\bf\large\underline\pink{Soution:-}$

R = 14 cm

as in 1 hr a full circle is completed by minute hand

therefore

distance covered by tip in 1 hr = circumference

circumference = 2πr

= 2 * 22/7 * 14

= 44 * 2

= 88 cm

therefore the tip moves 88 cm in one hour

Answer 2

Answer:

Step-by-step explanation:

60mins - 2 π r

15 mins - (2 π r) ÷ 4

              = π r ÷ 2

              = (22 × 14) ÷ 14

              = 22 cm
