Answer:
Given :-
The diameter of the flower bed is 56 cm.
Length of path surrounding it is 7cm.
To find :- Area of path.
Area of flower bed (circle) = πr ^2
= 22/7 x 56 ^2
= 22/7 x 3136
= 448 cm^2.
Flower bed - Path = 56 - 7 = 49cm.
Area of reduced part = πr ^2
= 22/7 x 49 ^2
= 22/7 x 2401
= 343 cm ^2.
Area of path = Area of flower bed - Area of reduced part
= 448 - 343
Area of path= 105 cm ^2
Answer :- Area of path is 105 cm^2.
