A chord of a circle subtends an angle of 60o at the length of a circle of radius 14 cm. Find the length of the chord
- 7 cm
-
14 cm
- 21 cm
- 28 cm
The correct answer is: B
Explanation
Chord Length (L) = \(2 \times Radius \times (sin \frac{angle}{2})\)
= \(2 \times 14 \times (sin \frac{60}{2})\)
= \( 28 \times (sin 30)\)
= \(28 \times \frac{1}{2}\)
= \(14cm\)
