The leash will serve as the radius of the circle that Adrianne's dog will be running around on.
radius = 9 feet long
Area = π r²
Area = π (9ft)²
Area = π 81ft²
Circumference = 2 π r
Circumference = 2 π 9ft
Circumference = 18ft π
The circumference of the circle that the dog will be forming when it runs around his leash is 18ftπ and the area it will cover will be 81ft²π.

Answer:
F = 120 N
Step-by-step explanation:
Given that,
The mass of the object, m = 20 kg
Acceleration of the object, a = 6 m/s²
We need to find the force exerted on an object. The force exerted on an object is given by :

So, the required force exerted on the object is 120 N.
