Answer:

Length of arc AB = 4π

Step-by-step explanation:

Formula to get the arc length is given by,

Length of arc = \frac{\theta}{360}(2\pi r)

Here, θ = central angle subtended by the arc AB

r = Radius of the circle

By substituting the values in the formula,

Therefore, length of arc AB = \frac{120}{360}(2\pi )(6)

                                              = 40π

Answer: Fraction of paint used for bird  house = \dfrac14

Step-by-step explanation:

Let quantity of the total paint be 1.

Given:  Fraction of paint to book shelf = \dfrac38

Fraction of Paint to leg = \dfrac14

Fraction of Paint left = \dfrac18

Let x= fraction of paint used for bird house.

Total paint = \dfrac38 +\dfrac 14+\dfrac18+x=1

\Rightarrow\ \dfrac{3+2+1}{8}+x=1\\\\\Rightarrow\ \dfrac{6}{8}+x=1\\\\\Rightarrow\ x=1-\dfrac68\\\\\Rightarrow\ x=\dfrac{2}{8}=\dfrac14

So, Fraction of paint used for bird  house = \dfrac14
