Answer:
32
/3 cm³
Step-by-step explanation:
If the diameter is 4 cm, then the radius is 2 cm.
Use the sphere volume formula:
V = 4/3
r³
Plug in the radius and solve:
V = 4/3
(2)³
V = 4/3
(8)
V = 32
/3
So, the volume of the sphere is 32
/3 cm³
Answer: The answer is -80
Step-by-step explanation:
2(2^2)+(3)(2)(−4)−4(−4)^2
2(2^2)+(3)(2)(−4)−4(−4)^2
=−80
