Question

Solve it plsssssssssssssssss.............

Measure of an arc of a circle is 80° & its radius is 18cm. Find the length of the arc.

Answer 1

Answer:

25.12 cm

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.

Therefore, Length of the arc = 25.12 cm.

Hope it helps!
