The circumference of oC is 56 cm. What is the length of AB (the minor arc)?
1 answer:
Answer:
Length of arc AB is 14. So, option E is correct
Step-by-step explanation:
Circumference of circle == 56 cm
We need to find length of arc AB?
Formula used will be l = rФ
We know, C = 2πr
56 = 2πr
56/2π = r
=> r = 8.91
Ф = 90° = 1.57 radians
So, l= rФ
l = 8.91 * 1.57
l = 13.98 = 14
So, Option E is correct

What are the choices? The answer should be around 870
Rule: (a/b)/(c/d)=(a/b)*(d/c)
(5/14)/(3/4)
(5/14)(4/3)
(5*4)/(14*3)
20/42
10/21
