Sagot :
Step-by-step explanation:
short hand radius = 4
distance travellled in 1 day revolution = 2πr= 2 x 22/7 x 4= 25.1cm (approx)
distance travellled in 2 day revolution= 25.1+ 25.1 = 50.2
long hand radius= 6
each hour 1 revolution by long hand so in 24 hr 24 revolutions and 48 he 48 revolution
distance travelled in 1 hr = 2πr= 2 x 22/7 x 6= 37.7
distance in 48hr = 37.7 x 48= 1809.6 (approx)
so sum of both= 1809.6 + 50.2 = 1859.8
Answer:
1910.12 cm
Step-by-step explanation:
2 days = 48 hrs = 2880 mins
One cycle of the short hand (4 cm) would be 12 hrs.
48/12 = 4 cycles
Circumference of a circle = [tex]2\pi r[/tex]
r = 4 cm
2*pi*4 ≈ 25.13 cm (I only rounded to the hundredth, adjust as u need)
25.13 * 4 = 100.52 cm
One cycle of the long hand (6 cm) would be 60 mins (which is 1hr and two days would be 48hrs or 48 cycles. But let's keep this consistent).
2880/60 = 48 cycles
Circumference of a circle = [tex]2\pi r[/tex]
r = 6 cm
2*pi*6 ≈ 37.70 cm (I only rounded to the hundredth, adjust as u need)
37.70 * 48 = 1809.6
100.52 + 1809.6 = 1910.12 cm
