Calculate the Perimeter of the Garden Section

A circular garden has a radius of 8 cm on a scale drawing. A 90° sector represents a small section of the garden that needs fencing.

r = 8cm 90° Arc 🌺 🌻 🌷
Given:
Radius (r) = 8 cm
Central Angle (θ) = 90°
π = 22/7
Formula:
Perimeter = 2r + Arc Length
Arc Length = (θ/360°) × 2πr
What is the perimeter of the section that needs fencing? Convert your answer to 2 decimal places.
Fill in your answer in the box provided:
Perimeter =
cm
