A circular wire of radius 3 cm is cut andbent so as to lie along the circumferenceof a hoop whose radius is 36 cm . Thenthe angle in degrees which is subtendedat the centre of hoop is​

Answer»

Answer:

30°(π/6)

Step-by-step EXPLANATION:

RADIUS of the circular wire =3 cm.

∴ Length of the circular wire = 2π × 3 = 6π cm

[Circumference = 2π R]

Radius of the hoop = 36cm.

Let θ be the angle SUBTENDED by the wire at the centre of the hoop. Then,

θ = arc/radius

θ =6π /36= π/6 = 30°
