Answer 2

Answer:

The area of the track is 160.14 m²

Step-by-step explanation:

Given that the trach is 3 m wide and the radius of the outer circle is 10 m.

Then the radius of the inner circle is

= (10 - 3) m = 7 m

The area of the outer circle is

= π * 10² m²

= 100π m²

and the area of the inner circle is

= π * 7² m²

= 49π m²

Therefore the area of the track

= area of the outer circle - area of the inner circle

= (100π - 49π) m²

= 51π m²

= 160.14 m²
