Question

Find the degree measure of the angle subtended at the center at a circle of radius 100cm by an arc of length 22cm use π=22/7

Answer 1

Answer:

12.6degrees or 12degrees 36 minutes

Step-by-step explanation:

angle in radian =length of arc / radius of circle

hence angle in radian = 22/100

angle in degrees = 360 / π +×angle in radians

this implies angle in degrees = (22×360)/(100π)

angle =(22×360×7)/(22×100) [using π=22/7]

angle =12.6degrees or 12degrees 36 minutes

I hope I answered the question .

Answer 2

$l = \frac{theta}{180} \times \pi \times r$

r=100 cm

l=22 cm

Theta =x

$22 = \frac{x}{180} \times \frac{22}{7} \times 100$

X=12.6°
