Answer:

6.6 cm and 14.6 cm

Step-by-step explanation:

(a)

the length of arc AB is calculated as

AB = circumference of circle × fraction of circle

= 2πr × $\frac{95}{360}$

= 2π × 4 × $\frac{95}{360}$

= 8π × $\frac{95}{360}$

= $\frac{8\pi (95)}{360}$

≈ 6.6 cm ( to the nearest tenth )

(b)

the perimeter (P) of sector AOB is

P = r + r + AB = 4 + 4 + 6.6 = 14.6 cm
