*⃣*⃣*⃣*⃣*⃣ ANSWER *⃣*⃣*⃣*⃣*⃣

==================================

Let the outer radius of the path be "R" metre and its inner radius be '' r '' metre.

==================================

According to question,

2 π R = 44

=> R = (44×7)/44 = 7 metre.

==================================

Area of the outer circle (surrounding circular path) = πR² = (22/7) × 7² m² = 154 m².

==================================

Now, inner radius will be (7-2) m or 5 m.


So, inner circumference = 2πr

= 2 × (22/7) × 5

= 31.42 m [REQUIRED ANSWER]
==================================

Area of inner circular pond

= πr²

= (22/7) × 25 m²

= 78.57 m²

==================================

Now, area of the path

= (154-78.57) m²

= 75.43 m² [REQUIRED ANSWER]
