Question

If measure of an arc of a circle is 160° and its length is 44cm find the circumference of the circle

Answer 1

Answer:

If measure of an arc of a circle is 160° and its length is 44 cm, find the circumference of the circle. Choose the correct alternative answer for the following question. (A) 66 cm.

Answer 2

Answer:

The circumference is approximately 22.8cm

Step-by-step explanation:

Using the formula θ = l/r, we get

                        => 160 = 44/r

                        => 160/44 = r

                        => 3.63cm = r

Thus, Radius (r) = 3.63cm

Therefore, Circumference = 2πr

                                            => 2 * 3.63 * 3.14

                                            => 22.79cm

                                            ≈   22.8cm
