Huu hapa utatuzi wa swali la 9: Swali la 9: Mchoro hapa chini unaonyesha gurudumu la gari la kuchezea. Je, nini kipenyo cha gurudumu ikiwa mduara wake ni 88 cm? A. 7 cm B. 28 cm C. 22 cm D. 14 cm Step 1: Andika formula ya mduara. Mduara wa duara (C) hutolewa na formula: C = 2 r ambapo r ni kipenyo na ni takriban (22)/(7). Step 2: Badilisha thamani ya mduara na kwenye formula. Tunapewa C = 88 cm. 88 = 2 × (22)/(7) × r Step 3: Tatua kwa r. Kwanza, zidisha namba upande wa kulia: 88 = (44)/(7) × r Ili kupata r, zidisha pande zote mbili kwa (7)/(44): r = 88 × (7)/(44) r = (88 × 7)/(44) Gawanya 88 kwa 44: r = 2 × 7 r = 14 cm Step 4: Linganisha jibu na chaguzi zilizotolewa. Kipenyo ni 14 cm, ambayo inalingana na chaguo D. Jibu sahihi ni: D) 14 cm Tuma swali linalofuata 📸
