Answer:
≈ 18.8 cm
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
The central angle is equal to the arc subtending it, that is 60°
arc = 2πr × 
= 2π × 18 × 
= 36π ×
= 6π ≈ 18.8 cm ( to 1 dec. place )
To divide mixed number, convert to improper fractions and divide them
(a/b)/(c/d)=(a/b)(c/d)=(ac)/(bd)
to multiply fractions, multily top by top and bottom by bottom
(a/b)(c/d)=(a times c)/(b times d)
Answer:
41 minutes 40 seconds
Step-by-step explanation:
10km = 10000m
10000/4 = 2500 seconds
2500/60 = 41.6666...
Hence, 41 minutes 40 seconds.
