4. Melissa is making this bird feeder with a metal roof for her craft store. She is leaving the cone open at the bottom. She needs to calculate the area of metal needed for the roof. Melissa made an error when she calculated the area of metal. Describe the error. Correct the solution. SA(roof) is the lateral area of cone SA= Trs = 7(20 cm) (30 cm) = 1884.955... cm2 I will need about 1880 cm² of metal for the roof. S = 30 base diameter = 20 cm
