Acircle has a radius of 5 cm. if the area is tripled, what happens to the circumference? asap

C.

Step-by-step explanation:

If the radius is 5, that means that from anywhere from the outside edge to the center is 5.

So, if you want to triple the area you have multiply the radius by 3, because a circle is not a oval, meaning that it is still the same all the way around.

The circumference is multiplied by √3.

Step-by-step explanation:

This quiz was a blur I don't know how I got this answer, sorry  

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.

the 3rd on is correct
