B = 3
3 to the second power is 9, and 4 • 9 = 36.
Answer:
9.42 cubic inches
Step-by-step explanation:
In order to find the volume for a sphere, we use the formula V = πr. For the sake of simplicity, we will be using 3.14 for π. Before we plug anything in, let's get our radius. Remember, the radius is half of the diameter.
Equation: d = 2r
Replace: 6 = 2r
Divide: 3 = r
Now that we have our radius, let's plug in what we have and solve.
Equation: V = 3.14r
Replace: V = 3.14(3)
Multiply: V = 9.42
Remember, volume is measured in cubic units, so use cubic inches for the unit here.
Answer:
They will pay the same amount!
The answer is X=3 or x=5/3
Answer:
X=-1,y=-2
Step-by-step explanation:
if y =2x
2x=4x+2
so X=-1 and y=-2
