Answer:
A dilation of 2 about the origin.
Step-by-step explanation:
You can see in the original figure the points are half the points of the transformed figure.
For example the coordinates of H are (0.5,0)
The coordinates of H' are (1,0)
Since 0.5 * 2 = 1
There is a dilation of 2 about the origin.
Answer:
90 degrees
Step-by-step explanation:
since angle A's exterior angle is 90 on a straight line then angle a is 90. 180-90=90 for the rest
The answer for this is 78
Angles c and e are vertical
Answer:
D. 9 cm
Step-by-step explanation:
The radius of the sphere can be found by solving the volume equation for the radius.
V = 4/3πr³
3V/(4π) = r³
r = ∛(3V/(4π)) = ∛(3×3052/(4×π)) ≈ ∛728.611
r ≈ 9.0 cm
The radius of the sphere is about 9 cm.
