Question

A circular flower bed is surrounded by a path 4m wide the diameter ofthe flower bed is 66m what is area of this path?

Answer

Perimeter of circular flower bed = $\large \sf \cancel \frac{66}{2}$=33m.

Radius of circular flower bed with 4m wide path (R) = 33+ 4

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 37m

Area of path = π R² - π r²

⠀⠀⠀⠀⠀⠀⠀⠀= π ( R² - r² )

⠀⠀⠀⠀⠀⠀⠀⠀= 3.14 ( 137 )² - (33))²

⠀⠀⠀⠀⠀⠀⠀⠀= 3.14 ( 1369 - 1089 )

⠀⠀⠀⠀⠀⠀⠀⠀= 3.14 ( 280 )

⠀⠀⠀⠀⠀⠀⠀⠀= 879.20 m²
