HELP ASAP PLEASE A running track in the shape of an oval is shown. The ends of the track form semicircles.

What is the perimeter of the inside of the track?

(π = 3.14)

392.00 m

372.22 m

444.44 m

588.88 m

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
