Question

measure of an arc of a circle is 80° and its radius is 18cm find the length of the arc(π=3.14)

Answer 1

This is the right answer of your question......

Answer 2

$\sf\:Answer:$

25.12 cm

$\sf\:Step-by-step- explanation:$

Let θ be the angle in a circle of radius r.

Given, θ = 80°, radius= 18cm.

∴ Length of arc = (θ/360°) * 2πr

                          = (80/360) * 2π(18)

                          = (8/36) * 2 * (3.14) * 18

                          = 25.12 cm.

$<b>Therefore, Length of the arc = 25.12 cm.$

Hope it helps!
