In this page length of arc question7, we are going to see quiz on the
topic length of arc. First we are going to see solution of question 7.

** Length of arc = (θ/360) x 2Πr**

here θ - angle formed by two radius

r - radius

**Question 7 :**

Find the length of arc whose radius is 14 cm and central angle is 288°

**Solution :**

Length of arc = (θ/360) x 2 Π r

Here central angle (θ) = 288° and radius (r) = 14 cm

= (288°/360) x 2 x (22/7) x 14

= (144/180) x 2 x 22 x 2

= (72/90) x 2 x 22

= (72/45) x 2 x 22

= (72 x 22 x 2)/45

= 3168/45

= 70.4 cm

Hence, the length of arc = 70.4 cm

(1) Find the length of arc whose radius is 42 cm and central angle is 60°

(2) Find the length of arc whose radius is 21 cm and central angle is 120°

(3) Find the length of arc whose radius is 35 cm and central angle is 72°

(4) Find the length of arc whose radius is 10.5 cm and central angle is 36°

(5) Find the length of arc whose radius is 14 cm and central angle is 5°

(6) Find the length of arc whose radius is 28 cm and central angle is 90°

(7) Find the length of arc whose radius is 14 cm and central angle is 288°

(8) Find the length of arc whose radius is 10.5 cm and central angle is 45°

(9) Find the length of arc whose radius is 35 cm and central angle is 18°

(10) Find the length of arc whose radius is 21 cm and central angle is 30°
