solving quadratic equations area problems- i already tried to firnd the answer key but couldnt but i will give brainliest to whoever can do this for me

 51.63 m²

Step-by-step explanation:

The relevant area formulas are ...

 A = πr² . . . . . area of a full circle of radius r

 A = LW . . . .  area of a rectangle of length L and width W

 A = 1/2bh . . . area of a triangle with base b and height h

__

The figure area is the sum of the areas of 1/2 a circle of radius 3 m, a rectangle with base 6 m and height 5 m, and a triangle with base 3 m and height 5 m. Using the above formulas, we find the area to be ...

 A = (1/2)(3.14)(3 m)² +(6 m)(5 m) + 1/2(3 m)(5 m)

 A = (14.13 +30 +7.5) m² = 51.63 m²

The area of the figure is about 51.63 m².

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.
