Answer:
Solid formed will be a CONE
Radius of the cone = 3 units
Step-by-step explanation:
Given points of a triangle are A(0, 0), B(3, 5) and C(0, 5).
Given triangle is a right triangle.
When the given triangle ABC is rotated about a line AC, a 3D image of a solid will be created in the form of a CONE.
This cone will have the radius = BC
Length of side BC = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
               = [tex]\sqrt{(3-0)^2+(5-5)^2}[/tex]
               = 3
Therefore, radius of the cone = 3 units
