Question

Find the area of a circular path 2 m wide surrounding a circular plot of radius 20 m

Answer 1

radius of circle r=20m
diameter of circle=40

diameter of circle=40+2
circle path
=42
radius of circle =42/2
including path
R=21m
area of path=(are of circle include path) - (are
of circle without path)
=π R^2-πr^2
=π(R^2-r^2)
=π (21*21-20*20)
=3.14(441-400)
=3.14*41
=128.74m^2
