Answer:
B) 113.1 cm³
Step-by-step explanation:
The cross-section of a sphere is a circle. The area of a circle is:
A = πr²
The largest cross section passes through the center of the sphere, where the radius of the circle equals the radius of the sphere.
28.27 = πr²
r = 3.00
The volume of the sphere is therefore:
V = 4/3 π r³
V = 4/3 π (3.00)³
V = 113.1
Answer:
<h2>Reflection and translation.</h2>
Step-by-step explanation:
The picture shows the preimage ABCD and the image A'B'C'D'.
Notice that both images are at the same distance from the x-axis, which implies a reflection across the x-axis. Them, the image was translated 1 units to the left.
Therefore, the right answers are reflection and translation.
