Would anybody like to learn about Quantum Physics? I am the teacher and I am here to teach others about a valuable topic?

what is quantum theory?

Step-by-step explanation:

Length of arc AB = 8.37m

Step-by-step explanation:

The formula for determining the length of an arc is expressed as

Length of arc = θ/360 × 2πr

Where

θ represents the central angle.

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Radius, r = 8 m

Angle subtended by the arc length of AB, θ = 60 degrees

Therefore,

Length of arc AB = 60/360 × 2 × 3.14 × 8

Length of arc AB = 8.37m rounded up to the nearest hundredth.
