Calculate the Perimeter of the Warning Sign

Engineer Achieng is designing a warning sign for a construction site in the shape of a sector of a circle. The sign has a radius of 10 cm and a central angle of 60°. She wants to know the total perimeter of the sign so she can estimate the length of reflective tape needed along its edges.

r = 10cm 60° Perimeter = ? ! 🏗️ 🦺 ⛑️ 🚧 ✨ ✨ ✨
Given:
Radius (r) = 10 cm
Central Angle (θ) = 60°
π = 3.142
Formula:
Perimeter = 2r + Arc Length
Arc Length = (θ/360°) × 2πr
Calculate the perimeter of the sector-shaped warning sign. Give your answer to 1 decimal place.
Select the correct answer from the choices given:
A
25.3 cm
B
28.4 cm
C
30.5 cm
D
32.1 cm
