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° |
