Sawa Sammybaraka, hebu tuangalie swali la kwanza. 1. Calculate the circumference of a circle whose radius is 1.68cm. Step 1: Kwanza, tafuta kipenyo (diameter) cha duara. Tunajua kuwa kipenyo ni mara mbili ya rediasi (D = 2r). D = 2 × 1.68 cm D = 3.36 cm Step 2: Tumia fomula ya mzingo wa duara, C = D. Tutatumia = (22)/(7). C = (22)/(7) × 3.36 cm Step 3: Fanya hesabu. C = 22 × (3.36)/(7) cm C = 22 × 0.48 cm C = 10.56 cm Mzingo wa duara ni 10.56 cm. That's 2 down. 3 left today — send the next one.
