Question

3 which of the following real - life situations is likely to involve a quadrilateral?
inflating a spherical balloon
building a pyramid with a triangle base
baking a 3 - layer circular cake
tiling a trapezoidal floor

Explanation:

A quadrilateral is a four - sided polygon. A trapezoid is a type of quadrilateral. Inflating a spherical balloon involves a sphere (a 3D shape, not a 2D quadrilateral). Building a pyramid with a triangle base has a triangular base (a 3 - sided polygon). Baking a 3 - layer circular cake involves circles (a 1 - sided closed curve in a sense, not a quadrilateral). Tiling a trapezoidal floor: a trapezoid is a quadrilateral (a four - sided polygon).

Answer:

tiling a trapezoidal floor
