Question

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
(B) 44 cm
(C) 160 cm
(D) 99 cm

Answer 1

Hope it helped you

We will solve this using the length of arc formula

Answer 2

Solution :

Given :

length of the arc ( l ) = 44cm

Measure of the angle (x) = 160°

Let the Circumference of the

circle = C

l = ( x/360° ) × C

=> C = ( l × 360° )/x

=> C = ( 44 × 360 )/160

=> C = 99

Option ( D ) is correct.
