\textbf {Hey there, here is the solution.}

.............................................................................................

STEP 1: Find the circumference:

Circumference = 2πr

Circumference = 2π(14) = 28π cm

.............................................................................................

STEP 2: Find the length of the arc:

Length of the arc = 36/360 x 28π

Length of the arc = 8.8 cm

.............................................................................................

Answer: The length of the arc is 8.8 cm

Length of the arc = θ/360°×πr²

6.6 = θ/360×22/7×14×14

6.6 = 154 × θ/90

θ = 594/154

θ = 3.857°
