Question

A rectangle with points (0,0), (3,0), (3, 7), and (0,7) is rotated around the y-axis. Which of the following is the vertical cross section of the three-dimensional figure formed? rectangle circle triangle cylinder

Answer 1

rectangle

Explanation:

Answer 2

we have that
A rectangle with points (0,0), (3,0), (3, 7), and (0,7)

using a graph tool
see the attached figure

if the rectangle is rotated around the y-axis
then
the three-dimensional figure formed is a cylinder with radius 3 units and height 7 units

and
the vertical cross-section is a rectangle with 6 units x 7 units

the answer is
rectangle
