Step-by-step solution
3 stepsHuu hapa ni ufumbuzi wa swali lako:
Andika formula ya eneo la uso wa tufe.
Eneo la uso wa tufe () linatolewa na formula:
ambapo ni rediasi ya tufe.
Tambua uhusiano kati ya asilimia ya hitilafu katika rediasi na asilimia ya hitilafu katika eneo la uso.
Kwa ujumla, ikiwa kiasi kinategemea kiasi kingine kwa uhusiano (ambapo ni kipimo kisichobadilika), basi asilimia ya hitilafu katika ni mara asilimia ya hitilafu katika .
Katika kesi hii, , hivyo .Kokotoa asilimia ya hitilafu katika eneo la uso.
Asilimia ya hitilafu katika rediasi () imetolewa kama .
Asilimia ya hitilafu katika eneo la uso () itakuwa:Asilimia ya hitilafu katika kipimo cha eneo la uso wa tufe ni .
