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 is 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; r 1 is the radius of the top, r 2 is the radius of the bottom, and h is the height of the lampshade.
