Question

The degree measure of the angle at the circle is θ. The length of an arc of the sector is

i) θπr/90
ii) θπr/180
iii) θπr/270
iv) θπr/360​

Answer 1

Answer:

Thus angle of θ will make a length = 360θ×2πr.

Answer 2

Answer:

The whole circle of 360 makes arc length of 2πr

Thus angle of θ will make a length = θ/360 ×2πr
