Rotation and translation are rigid transformations, they don't change figure sizes. Dilation change figure sizes increasing or decreasing them by scale factor.
First, find AB and A'B' by the formula:

As you can see AB=2A'B'. This means that the segment AB was decreased twice to form segment A'B'. Then the scale factor is 1/2.
First you need to find the radius. To do that you need to divide the diameter by two;
45 / 2 = 22.5
Then you plug the radius in the formula for a sphere. Which is...
V = (4 / 3)πr^3
First you need to find the volume with out pi
V = (4/3) π (45)^3
V= π (4/3) (91,125)
Your answer with out pi is...
V= (68,343.75) π cm^3
And with pi is...
V = 214,708.22 cm^3
Answer:
a. 8 cm
Step-by-step explanation:
Given:
EH = 6 cm
FG = 4.00 cm
Based on the mid-segment theorem of a trapezoid, we have:
EH = ½(FG + DI)
Plug in the values
6 = ½(4 + DI)
Multiply both sides by 2
6*2 = 4 + DI
12 = 4 + DI
12 - 4 = 4 + DI - 4
8 = DI
DI = 8 cm
