Question:

What is the length of the arc of a circle whose radius is 35 cm and arc subtends an angle of 36° at the centre of the circle? (Take π=22/7)

Options:

44 cm

22 cm

10 cm

220 cm

Correct Answer:

22 cm

Explanation:

We know ,

Length of an arc = 2 × π × r × \(\frac{θ}{360º}\)

= 2 ×  \(\frac{22}{7}\) × 35 × \(\frac{ 36º }{360º}\)

= 2 ×  22 × 5 × \(\frac{ 1 }{10}\)

= 22 cm
