Question 1 • FL-1205040-M/J Grade 7 Mathematics B -GF
Jalen says that the height, radius, and diameter of a cone lie entirely on the base of the cone. What is Jalen’s error?
Answer
A
The height does not lie on the base because it is perpendicular to the base.
B
The radius does not lie on the base because it contains the center of the base.
C
The diameter does not lie on the base because it contains a radius of the circle.
D
The base does not contain the height, the radius, or the diameter because it is a circle.
Explanation
The height of a cone runs from the vertex straight down to the base, perpendicular to the base’s plane; it is not entirely on the base. The radius and diameter are segments that lie in the circular base, so A correctly identifies Jalen’s error.
