Jerry bough a box of donuts and ate half of them himself. He gave one to each of his two sisters and had one left. How many donuts did he buy? Please help me. I need the answers ASAP, I would really appreciate it!

6 doughnuts

Step-by-step explanation:

if he gave 2 away and was left with 1, that means we know he had at least 3. He ate half ans after he had the 3 left, and obviously if you know basic math then you know that half of 6 is 3. That's why the answer is 6

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

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.
