Answer 1

Answer:

17pi/15

Step-by-step explanation:

s = r *theta where r is the radius and theta is the central angle in radians

Convert 51 to radians

51 * pi/180 = 51pi/180

s = 4 * 51pi/180

   = 17pi/15

Answer 2

Answer:

$Arc\ length = 3.6 cm$

Step-by-step explanation:

$Arc \ Length = 2 \pi r \frac{ \theta}{360}$

                 $= 2 \times \pi \times 4 \times \frac{51 }{360}\\\\=2 \times \pi \times \ 4 \times 0.142\\\\=3.5688 \\\\Arc\ length = 3.6 cm$
