Question

in a circle of radius 35cm, a chord subtends a 120 degree at the centre. find the angle of the corresponding minor segment and major segment

Answer 1

Answer:

Step-by-step explanation:

In any circle, the length of an arc (l) is proportional to the angle (θ) it creates (subtends) at the centre.

For a circle of radius r, the circumference will be 2π units.

Thus,

the length of the arccircumference=θ360∘,

so ∴ll2πr=θ360∘.=θ360∘×2πr=θ180∘×πr=r×π180∘×θ (Alternate formulations)
