Question

You can use the surface area formula for a right cone to find the surface area of an oblique cone . True or false?

Answer 1

The answer for the question shown above, is: False.
 The explanation is shown below:
 You cannot  use the surface area formula for a right cone to find the surface area of an oblique cone, because the slant height of oblique cones is on undefined and the vertex is not over the center. 

Answer 2

Answer:

False

Step-by-step explanation:

The surface area of a right cone is given by finding the area of the base and the lateral area.

The lateral area is the area of a sector of a circle whose radius is the height of the cone.

An oblique cone is always slanted and therefore the radius of the sector in one part would not be the same as the radius of the sector in another part.

Thus, the same formula can not be used to find both the surface area of the right cone and oblique cone.

Hence, we cannot use the  the surface area formula for a right cone to find the surface area of an oblique cone .
