Kevin's grandmother gave him an old lamp that needs a new lampshade. He wants to buy some fabric to make a new lampshade. The lampshade 10 inches tall The diameter of the top is 6 inches. The diameter of the bottom is 10 inches The formula for finding the lateral area of the shade is A= pi(r 1 +r 2 ) sqrt h^ 2 +(r 2 -r 1 )^ 2 where is the radius of the top, r 2 the radius of the bottom, and h is the height of the lampshade. Select the area that is the best apptoximation for the amount of fabric he needs to buy.

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
