For sp3d hybridized central atoms, the only possible molecular geometry is trigonal bipyramidal.
Hybridisation (or hybridization) is a process of mathematically combining two or more atomic orbitals from the same atom to form an entirely new orbital different from its components and hence being called as a hybrid orbital.
In this case, if all the bonds are in place, the shape is also trigonal bipyramidal.
In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid.
Bond angle(s): 90°, 120°
Coordination number: 5

Answer:
x = 6
Step-by-step explanation:
Answer:
87
Step-by-step explanation:
66 + 72 + 87 = 225
225 / 3 = 75
C=2pi*r; circumference formula
a=pi*r^2; area formula
It says the circumference is pi/2; so undo that by using the circumference formula to solve for r(radius);
2pi*r=pi/2
pi crosses each other off, making 2r=1/2
(When something crosses itself out it becomes a 1)
2r=1/2
r=.25 (because 1/2 is 0.5, and 0.5 divided by 2 is .25)
Now use the r you have in the area formula.
a=pi*r^2
.25 squared is .0625
1 divided by .0625 is 16, so now you have
a=pi*.0625 this will get you 1/16th of pi, or pi divided by 16.
(1/16th if pi is the same as pi divided by 16)
.0625pi=pi/16
Dividing integers is the opposite of multiplying integers.
