Acircle has a radius of 11 feet. what is the length of an arc of that circle that is captured by a central angle that measures 108

The length of arc of the circle is 20.73 feet.

Step-by-step explanation:

A circle has a radius of 11 feet.

The length of an arc of that circle that is captured by a central angle that measures 108°

Formula:

where,

First we will change degree to radian.

Hence, The length of arc of the circle is 20.73 feet.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
