Composite figures are two or more figures combined. when finding the surface area, you cannot simply find the separate surface areas and add them. what face(s) do you have to exclude from the total surface area? explain.

Step-by-step explanation:

You must exclude any intersecting faces (faces that are shared), because these faces are not on the surface.

For example, an ice cream cone can be approximated as a composite figure of a hemisphere on top of a cone.  The circular base of the hemisphere and the circular base of the cone are intersecting, so you must exclude it when finding the surface area.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
