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 tall. The diameter of the top is 6 inches. The diameter of the bottom 10 inches. The formula for finding the lateral area of the shade A= pi*(r 1 +r 2 ) sqrt h^ 2 +(r 2 -r 1 )^ 2 where topthe radius of the bottom, and h is the height of the lampshade. r 1 is the radius of the Select the area that is the best approximation for the amount of fabric he needs to buy.
