Question

Find the length of each arc, Round your answas to the nearest tenth. Use 3.14 for

pi. Show your work.

Answer 1

58.6 cm;

20.1 m

Explanation:

✔️Length of arc = θ/360 × 2πr

Where,

θ = 240°

r = 14 cm

π = 3.14

Plug in the values:

Length of arc = 240/360 × 2 × 3.14 × 14

= 58.6133334 = 58.6 cm (nearest tenth)

✔️Length of arc = θ/360 × 2πr

Where,

θ = 105°

r = 11 m

π = 3.14

Plug in the values:

Length of arc = 105/360 × 2 × 3.14 × 11

= 20.1483334 = 20.1 m (nearest tenth)
