Which, if any, of the following statements about the formulas for the surface area of a pyramid and the surface area of a cone is incorrect?

A. Both of the formulas for the surface area are of the form "S. A. = L. A. + B".
B. The formulas for the lateral area are different.
C. The formulas for the base are different.
D. All of the above are correct.

B HOPE DIS HELPS:)

Step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
