Answer:
3.338 m²
Step-by-step explanation:
Diameter. = 4 metres
Radius. = 2 metres
Radius = 200 cm
Area = πR² = π(200)²
Now Radius of outer circle = 200 + 25
= 225 cm
Area of outer circle = π(225)²
Area of path = Area or Outer circle - Area of inner Circle
= π(225)² - π(200)²
= π ( 225² - 200²)
= π(10625)
= 33380 cm²
= 33380/10000 m²
= 3.338 m²
