(a) $A = 201~ft^2$ (b) 3 quarts (c) $47.67 #### Work Step by Step (a) We can find the area:$A = \pi~r^2A = (\pi)(8~ft)^2A = 201~ft^2$(b) We can find the number of quarts required:$\frac{201~ft^2}{70~ft^2/quart} = 2.9$Since paint is sold in quarts, we need to buy 3 quarts of paint. (c) We can find the cost:$cost = (\$15.89)(3) = \$47.67\$
