Ответ:
the area is 314 ft²
Step-by-step explanation:
if the chain can move around the tree, then the path along which the dog can move is a circle whose radius is the length of the chain.
The formula for determining the area of a circle is expressed as
Area of circle = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Therefore, the area that the dog has to play if the chain can move around the tree is
3.14 × 10² = 314 ft²
