Problema Solution
A circular flower bed is 24 m in diameter and has a circular sidewalk around it that is 2 m wide. Find the area of the sidewalk in square meters
Answer provided by our tutors
The area of the sidewalk = The total area - The area of the flower bed
The area of the sidewalk = ((24/2)+2)^2pi + (24/2)^2pi
The area of the sidewalk =14^2pi + 12^2pi
The area of the sidewalk = (196 - 144)pi
The area of the sidewalk = 52pi (pi = 3.14)
The area of the sidewalk = 163.28 m^2
