Circular flower bed is 24 m in diameter and has a circular sidewalk around it that is 3 m wide. find the area of the sidewalk in square meters. use 3.14 for pi.

Respuesta :

TIANCHIbcj
radius:24/2=12 m
the area of the sidewalk:3.14*(12+3)^2-3.14*12^2=3.14*81=254.34m^2

The area of the sidewalk in square meters is 254.34 m²

What is Area of circle?

The area of a circle is pi times the radius squared (A = π r²).

Given: diameter: 24m

          inner  radius= 12m

  outer radius = 12+3

                      = 15 m

Area of side walk will be,

=π(R²-r²)

=3.14(15²-12²)

=3.14*(225-144)

= 3.14*18

= 254.34 m²

Hence, the area of side walk is 254.34 m³
