Answer:
If we convert the height to meters like this:
And we want to find the volume of the cone and is given by:
And replacing we got:
Step-by-step explanation:
For this case we have a right circular cone with a height of 9.6cm and a base with a diameter of 2.9m. We can find the radius like this:
If we convert the height to meters like this:
And we want to find the volume of the cone and is given by:
And replacing we got:
Option D: is the solution to the inequalities.
Explanation:
From the given graph, we can see that the equation of the inequalities are
and
To determine the coordinate that satisfies the inequality, let us substitute the coordinates in both of the inequalities and
Thus, we have,
Option A:
Substituting the coordinates in and
, we get,
is not true.
is true.
Since, only one equation satisfies the condition, the coordinate is not a solution.
Hence, Option A is not the correct answer.
Option B:
Substituting the coordinates in and
, we get,
is not true.
is not true.
Since, both the equations does not satisfy the condition, the coordinate is not a solution.
Hence, Option B is not the correct answer.
Option C:
Substituting the coordinates in and
, we get,
is not true.
is true.
Since, only one equation satisfies the condition, the coordinate is not a solution.
Hence, Option C is not the correct answer.
Option D:
Substituting the coordinates in and
, we get,
is true.
is true.
Since, both equation satisfies the condition, the coordinate is a solution.
Hence, Option D is the correct answer.
