Question

I need feedback please. I don’t know how to solve this.

Answer 1

s = 11π/9 units

Explanation:

The arc length formula is s = rФ, where Ф is the central angle in radians.

Here the central angle is given as 44° and must be converted to radians:

44° π

------ * ----- = 11π/45 radians

1 180°

The length of arc MAN (not MPN) is s = (5 units)(11π/45 radians), or

s = 11π/9 units

Answer 2

79/9 * pi

Explanation:

First find the circumference of the entire circle

C = 2 pi r

C = 2* pi* 5

C = 10 pi

The degree of MPN is 360 - 44 = 316

The fraction of the circle is 316/360 =79/90

Multiply that by the total circumference

79/90 * 10 pi

79/9 * pi
