Question

PLZ HELP ASAP ROTATE 2D SHAPES IN 3D

Answer 1

The solid 3D object that produced by rotating the triangle a bout line m.
The correct choice is (c)
A cone with radius 8 units

because the vertex that exist on line m will not changed that represent the vertex of the cone
and the base of the triangle will represent the diameter of the cone will be equal = 16
So the radius will be equal 8
and the height of the cone will be equal 6

Answer 2

A cone with a radius of 8 units solid 3D object that is produced by rotating the triangle about line m.

What is the vertex of a cone?

When you are talking about a POLYHEDRON (and not just any three-dimensional object!), a vertex is a point where three OR MORE edges meet.

When you are talking about a cone, a vertex is a point where the straight lines that form the side of the cone meets.

The vertex that exists on line m will not be changed that represents the vertex of the cone.

• The base of the triangle will represent the diameter of the cone will be 16.

• The radius will be 8.

• The height of the cone will be 6.

Hence, a cone with a radius of 8 units solid 3D object that is produced by rotating the triangle about line m.
