Question

Consider Circle Y with radius 3 m and m XYZ=70

What is the approximate length of minor arc XZ? Round to the nearest tenth of a meter.

Answer 1

4.9m

Explanation:

In circle Y:

Radius=4m

Central Angle of XYZ=70°

Length of an arc
`=(\theta)/(360^\circ)X2 \pi r`

Therefore, Length of minor arc XZ

`=(70^\circ)/(360^\circ)X2X4 X \pi`

=4.9m (correct to the nearest tenth)
