Sam drew a picture of a snowman by drawing three circles on top of each other. The bottom circle had a radius of 3 inches, the middle circle's diameter was 4 inches, and the top circle had a radius of 1 inch. Find the total area of Sam's snowman to the nearest square inch.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
