Answer:
C is your answer good sir
The formula for volume of a sphere is:
V = 4/3 * PI * r^3
Replace r with with given radius:
V = 4/3 * pi * 17^3
V = 4/3 * PI * 4913
You don't give the choices, but anything like the two equations I gave could be correct. Might even multiply the 4/3 by r^3?
If you list the choices I can tell you which one.
Answer:
1000 m³
Step-by-step explanation:
The base of a cube is just a square.
The area of a square is , where l is the length.
Since we know the area of the base (the square) we can find l easily.
Now that we know the length of the sides, we have to take note that a cube has side lengths that are all congruent.
This means the height of the cube is also 10m.
Since the volume of a cube is represented as , where l is the length, we can substitute 10 in as to find it's total volume.
So the volume of this cube is 1000 m³.
Hope this helped!
Answer:
3.458×10¹⁷ kg
Step-by-step explanation:
(3.5×10⁻² kg/L) × (9.88×10¹⁸ L) = (3.5×9.88) × 10⁽⁻²⁺¹⁸⁾ kg
... = 34.58×10¹⁶ kg
... = 3.458×10¹⁷ kg

<em>Comment on significant digits</em>
It would be appropriate to round the answer to 2 significant digits, matching the number of significant digits in the least-precise factor. Then the answer would be 3.5×10¹⁷ kg.
