Question

Consider circle Y with radius 3 m and central angle XYZ measuring 70°. What is the approximate length of minor arc XZ? Round to the nearest tenth of a meter.

Answer 1

R = A / tetha

70° × pi/180 = radian
radian = 1.222 rad

3 = A / 1.222
Arc = 3.7 meter

i am a mathematics teacher. if anything to ask please pm me

Answer 2

r = A / tetha

70° × pi/180 = radian

radian = 1.222 rad

3 = A / 1.222

Arc = 3.7 meter
