Hurry! A class measured the radius and circumference of various circular objects. The graph.
Question A: does there appear to be a proportional relationship between the radius and circumference of the circle? Explain
Question B: why might the measured radius and circumference not be exactly proportional?

72 is the answer to this problem

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

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.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
