Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Alan has 8 pine trees in his backyard and each tree drops 200 pine cones. If 30% of the pine cones fall on Alan's roof, and each pine cone weighs 4 ounces, how many ounces of pine cones does Alan have on his roof?

### Response:
 Kwanza tafuta idadi jumla ya mikonge: miti 8 * mikonge 200/mti = <<8*200=1600>>1600 mikonge
Kisha, mara idadi hiyo na 30% ili kujua ni mangapi yanadondoka kwenye paa la Alan: mikonge 1600 * 30% = <<1600*30*.01=480>>480 mikonge
Kisha, mara idadi hiyo na uzito wa kila mchonge ili kupata uzito jumla wa mikonge: mikonge 480 * unga 4/mchonge = 1920 unga
