C. 4,840 ft³
D. 6,032 ft³
The volume of the cone is 4840 cubic ft if the diameter of the base is 34 feet and the height is 16 feet option (C) is correct.
It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.
Volume can be defined as a three-dimensional space enclosed by an object or thing.
It is given that:
A pile of tailings from a gold dredge is in the shape of a cone.
The diameter of the base is 34 feet and the height is 16 feet.
As we know,
The volume of the cone is given by:
r = 34/2 = 17 ft
h = 16 feet
Plug the above values in the formula:
After solving:
V = 1541.33π cubic feet
Take π = 3.14
V = 1541.33(3.14) cubic feet
V = 4839.78 ≈ 4840 cubic ft
Thus, the volume of the cone is 4840 cubic ft if the diameter of the base is 34 feet and the height is 16 feet option (C) is correct.

The formula for the volume of a cone is:
Therefore,
B.) none of these
C.) are the same length
D.) are the not same length
The best answer is the diagonals of the rectangle are the same length.
The diagonal of rectangle is a line segment drawn between the opposite vertices of the rectangle. The properties of diagonals of a rectangle are as follows:
1. The two diagonals of a rectangle are congruent. In other words, the length of the diagonals is equal.
2. The two diagonals bisect each other and divide the rectangle into two equal parts.
3. The length of the diagonal of rectangle can be obtained using the Pythagoras theorem.
4. When the diagonals bisect each other, the angles of a rectangle at the center become one obtuse angle and the other an acute angle.
5. When two diagonals bisect each other at 90° it is called a square.
6. Since the diagonal of rectangle divide the rectangle into two right-angled triangles, it is considered the hypotenuse of these triangles.
We know the diagonal property of rectangle that
1. The diagonals of the rectangle bisect each other.
2. The diagonals of the rectangle are equal.
The best answer is the diagonals of the rectangle are the same length.

C.) Are the same length
How you know-
No matter how long the rectangle is the diagonals always will measure the same length. Think about two sides of a square, they have to equal the same length because if they were not the same then the shape wouldn't be a square.
