Answer:

B 6.3

Step-by-step explanation:

r = 8

l = 2*3.14*r

l = 50.24

s=l/360*45

For this case we have that by definition, the arc length is given by:

[tex]Al = 2 \pi * r *\frac {a} {360}[/tex]

Where:

r: It's the radio

a: It is the angle of the sector

Then, according to the data we have:

[tex]Al = 2 \pi * 8 * \frac {45} {360}\\Al = 2 * 3.14 * 8 * \frac {45} {360}\\Al = 50.24 * \frac {45} {360}\\Al = 6.28[/tex]

Rounding we have 6.3in

Option B
