Question

a circular wire is cut and placed along the hoop of a circle of 3 times its radius.find the angle subtended.plzzz answer.......​

Answer 1

Answer:

Explanation:

Circumference of wire of Radius 3 cm = 2π x 3 = 6π

Now because this wire is cut and placed along circle with a radius of 40 cm

PQ will be the length which will be acquired by this circle

it is known that the length of the arc is θ2πr/2π

now we will put the values in it  

6π = θ2π x 40/2π  

θ = 6π /40

θ = π/6.6 is the Answer

Answer 2

Answer:

Circumference of wire of Radius 3 cm = 2π x 3 = 6π

Now because this wire is cut and placed along circle with a radius of 40 cm

PQ will be the length which will be acquired by this circle

it is known that the length of the arc is θ2πr/2π

now we will put the values in it  

6π = θ2π x 40/2π 

θ = 6π /40

θ = π/6.6 is the Answer
