For this case we have by definition, that the volume of a cone is given by:
Where:
A: It is the cone radius
h: It's the height
They tell us that the diameter is 21 m, then the radius is half the diameter, that is: 10.5m. The height is 4m. Substituting the data:
.
Finally, the volume of the cube is
ANswer:
Option B
Answer:
A. -4 and 4
B. No solution.
Step-by-step explanation:
The given equation is
A.
Equate the denominators equal to 0 to find the restrictions on the variable.
Therefore, .
B.
We have,
Multiply both sides by (x-4)(x+4).
Add 4 on both sides.
Divide both sides by 5.
Here the solution is x=4 but it is the restricted value.
Therefore, the given equation has no solution.
