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.

The number of parents is c -9 since there are 9 more children than parents
And we know that the total number of people in the room is 25 so:
c + c-9 = 25
or
2c - 9 = 25
We can then solve for c
2c = 34
c = 17
Step 1) y=16-x2. Swap the sides so that all terms of the variables are on the left side. Step 2) 16-x_{2}=y. Subtract 16 from both sides. Step 3) -x_{2}=y-16 Divide the two sides by -1. Step 4). \frac{-x_{2}}{-1}=\frac{y-16}{-1} Dividing by -1 undoes the multiplication by -1. Step 5). x_{2}=\frac{y-16}{-1} Step 6) dived y-16 by -1 And the final answer = x_{2}=16-y
