Answer:
11.5 cm^3
Step-by-step explanation:
The volume of a sphere is (4/3)(pi)(r^3). To find the radius, divide the diameter of 2.8 to get 1.4. Then plug it in to get 11.49. 11.49 rounded to the nearest tenth is 11.5 cm^3.
For 12a, they are asking about winter sports, they could ask about all sports.

For 13b, I believe it should be discreet, and once again apologize for not knowing the types of graphs.
Answer:
Step-by-step explanation:
Answer:
(3 + 4i) + (8 + 2i) = 3 + 4i + 8 + 2i
(3 + 4i) + (8 + 2i) = (3 + 8) + (4i + 2i)
(3 + 4i) + (8 + 2i) = 11 + 6i
