Question

the duametre of a circular park is 42 m a 3m path is around it find area of the path​

Answer 1

Answer:

Area of path is 424 m² (approx.)

Step-by-step explanation:

diameter of circle = 42 m

therefore, radius = 21 m

Area of circle (C1) = πr²

= 1386 m²

Now, 3m wide path is made around it..

So the radius becomes = 21 m + 3 m = 24 m

Area of circle (C2) = πr²

= 1810 m²

Area of path = C2 - C1

= 1810 - 1386

≈ 424 m²
