Given: a circular path of uniform width 3m surrounding a circular region of radius 10m is
To Find : The area of a circular path
Solution:
surrounding a circular region of radius 10m
Hence inner radius r = 10 m
a circular path of uniform width 3m
Hence outer radius = inner Radius + width
=>outer radius R = 10 + 3 = 13 m
Area of circle = π ( radius)²
area of a circular path = πR² - πr²
= π ( 13² - 10²)
= 69π
≈ 216.77 m²
Area of a circular path is 69π or ≈ 216.77 m²
