The intersection of a right cylinder and a plane makes an oval cross section. which option is true about the plane of intersection?
the right cylinder is cut with a plane parallel to the base.
the right cylinder is cut with a plane perpendicular to the base and passing through the center.
the right cylinder is cut with a plane perpendicular to the base but not passing through the center.
the right cylinder is cut with a plane that is neither parallel nor perpendicular to the base.

The right cylinder is cut with a plane that is neither parallel nor perpendicular to the base.

Step-by-step explanation:

Given: The intersection of a right cylinder and a plane makes an oval cross section.

The only method to get an oval cross is "the right cylinder is cut with a plane that is neither parallel nor perpendicular to the base."

If the right cylinder is cut with a plane parallel to the base then shape of cross section will be circle.

If the right cylinder is cut with a plane perpendicular to the base and passing through the center then shape of cross section will be rectangle.

If the right cylinder is cut with a plane perpendicular to the base but not passing through the center then again shape of cross section will be rectangle.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
