Question

Match Term Definition

Triangle A) shape created when a rectangle is rotated about the y-axis
Rectangle B) perpendicular cross section of a cylinder
Circle C) parallel cross section of a sphere
Cylinder D) perpendicular cross section of a pyramid
Cone E) shape created when a right triangle is rotated about the y-axis

Answer 1

Perpendicular cross section of a pyramid ------- triangle.

Perpendicular cross section of a cylinder ------- rectangle

parallel cross section of a sphere ------ circle

shape create.... ----- cylinder.

Explanation:

Imagine you cut pyramid like that. Height of pyramid would be height of your triangle. and sides of pyramid would be sides of triangle.

diameter of a base of cylinder would be one side of rectangle and height of cylinder would be other side of rectangle. (pair of sides)

when you cut sphere a side would apear with shape of circle.

one side of rectangle would be hight of cylinder and other would be radius of it.

last one is cone. If you place right angle in coordinate beginning (0.0) and one of shorter sides to lie on y axis other would be on x axis. when rotated you get cone.
