\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

hope it helpssss
Mark it as brilliant answer plzzz
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°
