A circular flower bed is 20 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk in square meters. Use 3.14 for it.
The area of the sidewalk is m2.
(Round in the neare

diameter = 20m, sidewalk =2m

a

Step-by-step explanation:area of the flower bed = pie r square . 3.14 x 10 x 10

= 314.00m SQ

area of flower bed = pie r square

=3.14 x 8 x 8

= 200.96 m sq

side walk = incl area - excl area= 314 - 200.96 = 113.4m sq

it would rotate about 180 degrees.
