Answer 1

#1

We are given,

• θ = 30°
• Radius = 9cm

Length of arc is given by,

`\sf(θ)/(360) * 2\pi r`

`\sf (30)/(360) * 2 * (22)/(7) * 9`

`\sf \frac{ \cancel{30}}{ \cancel{360}} * 2 * (22)/(7) * 9`

`\sf \frac{1}{ \cancel{120}} * \cancel2 * (22)/(7) * 9`

`\sf \frac{1}{ \cancel{60}} * (22)/(7) * \cancel9`

`\sf \frac{1}{ \cancel{20}} * \frac{ \cancel{22}}{7} * 3`

`\sf (1)/(10) * (11)/(7) * 3`

`\sf (33)/(70) \approx0.4cm`
