Question

A wire 96 CM long is bend, so as to lie along the arc of a circle of 180 CM radius the angle subtended at the centre of the arc in degree is


please help me ​

Answer 1

Answer:

Total length of wire = 121cm

Radius. = 180cm

We know that length of arc = radius × angle substented in radians

Therefore,

121.=.180× angle in radians

Angle=

180

121

Angle in radians= 0.6722

Angle in degrees =

3.14

(angleinradians×180)

=

3.14

121

=38.53 degrees

Hence angle substented is 38.53 degrees
