In a circle of radius, 14 cm. an arc subtends an angle of 90° at the center. The length of the arc (in cm) is equal to: (Take )
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 22.
Given that
A circle of radius (r) = 14 cm
An arc subtends an angle of = 90° at the centre
Arc length (l) = rθ × π/180
l = 14 × 90 × (22/7)/180 = 22 cm
