Respuesta :

2 × pi × 5 × 135 / 360 = 11.8

Answer:

Arc length = 11.8 cm.

Step-by-step explanation:

Given  : A circle with radius = 5 cm , central angle = 135°.

To find :  what is the length of arc AB.

Solution : We have given  circle with radius = 5 cm , central angle = 135°.

Arc length = [tex]\frac{theta}{360} * 2*\pi * radius [/tex].

Plug the values radius = 5 cm , central angle = 135°.

Arc length = [tex]\frac{135}{360} * 2* 3.14 * 5 [/tex].

Arc length = [tex]\frac{135}{360} * 31.4 [/tex].

 Arc length  = 0.375 * 31.4 .

   Arc length = 11.775 cm.

Therefore,  Arc length = 11.8 cm.
