Acylindrical garbage can has a radius of 2.8ft and holds 86.21 cubic feet of trash. whats the height? a) 3.5ftb) 9.8ftc) 5.2ftd) 1.9ft

Correct choice is A

Step-by-step explanation:

The volume of the cylinder can be calculated using formula

where r is the base circle radius  and h is the height of the cylinder.

In your case,

then

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

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.
