Question

Which of the following is the most precise description for the net of a cylinder?

(A) 1 rectangle and 2 circles
(B) 1 square and 1 circle
C) 1 rectangle and 1 circle
(D) 2 squares and 1 circle

Answer 1

The net of a cylinder consists of 1 rectangle and 2 circles, representing the sides and bases when unfolded into a two-dimensional shape.

Step-by-step explanation:

The most precise description for the net of a cylinder is (A) 1 rectangle and 2 circles. A net is a two-dimensional shape that can be folded into a three-dimensional object. For a cylinder, the net consists of a rectangle that forms the cylindrical surface and two circles that form the top and bottom bases of the cylinder. To visualize this, imagine unwrapping a paper towel roll; the body of the roll would lay out flat as a rectangle, while the ends would be circles. When considering fitting a circle within a square, the diameter of the circle is equal to the side length of the square (a = 2r). Thus, the perimeter and area of the circle would be less than that of the square the circle fits within.
