Step 1: Tafuta eneo la duara la kwanza. Radiasi ya duara la kwanza, r_1 = 9 cm. Eneo la duara la kwanza, A_1, linahesabiwa kwa kutumia fomula A = r^2. A_1 = (9 cm)^2 A_1 = 81 cm^2 Step 2: Tafuta radiasi ya duara la pili. Eneo la duara la pili, A_2, limepewa kama 16 cm^2. Acha r_2 iwe radiasi ya duara la pili. Tunajua A_2 = r_2^2. 16 cm^2 = r_2^2 Ili kupata r_2^2, tunagawanya pande zote mbili kwa : r_2^2 = (16)/() cm^2 Ili kupata r_2, tunachukua mzizi wa mraba wa pande zote mbili: r_2 = sqrt((16)/()) cm r_2 = (4)/(sqrt()) cm Step 3: Kokotoa thamani ya d (kipenyo cha duara la pili). Kipenyo d ni mara mbili ya radiasi r_2. d = 2 r_2 d = 2 × (4)/(sqrt()) cm d = (8)/(sqrt()) cm Thamani ya d ni: (8)/(sqrt()) cm Hili ndilo la mwisho la bure leo — litumie vizuri kesho, au andika /upgrade kwa maswali yasiyo na kikomo.
