Answer 1

To find the radius of the cone, we first need to understand the relationship between the radius, height, and slant height.

In a right cone, the slant height, height, and radius form a right triangle, where the slant height is the hypotenuse, the height is one of the legs, and the radius is the other leg.

Using the Pythagorean theorem, we have:

(radius)^2 + (height)^2 = (slant height)^2

Substituting the given values:

(radius)^2 + (12)^2 = (10)^2

Simplifying the equation, we have:

(radius)^2 + 144 = 100

Subtracting 144 from both sides:

(radius)^2 = 100 - 144

(radius)^2 = -44

Since the radius cannot be negative, there is an error in the image or given values. Therefore, we cannot determine the radius of the cone based on the given information.

edge.

Answer 3

The correct answer is "vertex." The point on a cone where two or more line segments meet is called the vertex.

Answer 5

The radius of a cylinder is half of its diameter. In this case, the diameter is 16 units. Therefore, the radius would be half of 16, which equals 8 units.

So the correct answer is "8 units."
