NEED ANSWERED ASAP!!

A 3-dimensional figure is intersected by a plane horizontally such that the intersection of the figure and the plane is a circle-shaped cross-section. Which of the following can NOT be the 3-dimensional figure?
1. sphere
2. cube
3. cone
4. triangular prism
5. square pyramid

Answer 1

the correct one is option 1.sphere

Answer 2

2nd , 4th and 5th option are correct that is Cube, Triangular prism and Square pyramid can not be 3-Dimensional Figure.

Explanation:

Given: A 3-Dimensional Figure.

A circular cross sectional plane is obtained when a plan horizontally intersect with the 3-Dimensional Solid figure.

To find: From given Solid figures which can to be our required figure.

Since we get a circular cross sectional plane figure. which means Surface on the side of the 3-Dimensional figure must be curved.

So, from given options Only sphere and cone has curved surface in sides.

Therefore, 2nd , 4th and 5th option are correct that is Cube, Triangular prism and Square pyramid can not be 3-Dimensional Figure.
