What is kinematics ???
don't explain !!!​

Kinematics is the branch of classical mechanics that describes the motion of points, objects and systems of groups of objects, without reference to the causes of motion (i.e., forces ).

hope it helps

Hii abh yha aay aap bahut bahut aaabar aaabrr aapka

the answer is

r ≈5.641

plug in the area of 100 yards into the equation

100=

divide each side by pi

≈ 31.8309=

take the square root of each side to find r

=r

r ≈5.641

can you give me a hint
