Question

A circular flower bed with a radius of length 5 m is surrounded by a gravel walk 1 m wide. What is the area of the gravel walk?

Answer 1

Step-by-step explanation:

AREA OF GRAVEL WALK = AREA OF TOTAL SURFACE -AREA OF CIRCULAR BED

AREA OF CIRCULAR BED = PIE R^2

=22/7 ×5×5

=22/7×25

=22×25/7

=78.57

AREA OF TOTAL SURFACE = PIE R^2

=22/7×6×6

=22/7×36

= 113.14

AREA OF GRAVEL WALK = 113.14 - 78.57

= 34.57
