Question

find the radius,arc length and area of the following sectors a) perimeter=183 cm angle=135​

Answer 1

Answer:

radius = 29.14 , arc length = 21.9$\pi$ , area = 2666.3

Step-by-step explanation:

radius = perimeter/2$\pi$

radius = 183/6.28

radius = 29.14

arclength = rФ

                = 21.94 (135)  = 21.94(3$\pi$/4)

                = 21.9$\pi$

area = $\pi$rsq

       = 3.14(29.14)(29.14)

        = 2666.3
