Answer: 1/2
Step-by-step explanation:
For the answer to the question above,
<span>the angle of 360 ° → π.d </span>
<span>the angle of x ° → 8π </span>
<span>You make the cross-multiply and you can get: </span>
<span>x * π.d = 8π * 360 </span>
<span>x * d = 8 * 360 </span>
<span>x = 8 * 360/d → where d = 2r </span>
<span>x = 8 * 360/2r </span>
<span>x = 4 * 360/r → where r = 4.5 cm </span>
<span>x = 4 * 360/4.5 </span>
<span>x = 320 °</span>
