Answer now ! what is the measure in radians for the central angle of a circle whose radius is 9 cm and intercepted arc length is 7.2 cm? enter your answer as a decimal in the box.*don't put down any answer just for pointsfor anyone who needs the answer, it's 0.8.

0.8 radian

Step-by-step explanation:

Arc length formula:  s = r(theta).  This can be solved for the central angle, theta:  theta = s / r.  Subbing 7.2 cm for the arc length (s) and 9 cm for the radius, we get theta = s / r = (7.2 cm) / (9 cm) = 0.8 radian

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.
