Ili kupata mzingo wa duara, tunatumia formula C = 2 r, ambapo C ni mzingo, ni pi, na r ni rediasi. Katika swali hili, tunatumia = 3.14. a) Step 1: Tambua rediasi (r). Rediasi ya duara ya kwanza ni r = 2.45 cm. Step 2: Tumia formula ya mzingo. C = 2 r C = 2 × 3.14 × 2.45 cm Step 3: Hesabu mzingo. C = 6.28 × 2.45 cm C = 15.386 cm Mzingo wa duara a) ni 15.386 cm. b) Step 1: Tambua rediasi (r). Rediasi ya duara ya pili ni r = 4.2 cm. Step 2: Tumia formula ya mzingo. C = 2 r C = 2 × 3.14 × 4.2 cm Step 3: Hesabu mzingo. C = 6.28 × 4.2 cm C = 26.376 cm Mzingo wa duara b) ni 26.376 cm. c) Step 1: Tambua rediasi (r). Rediasi ya duara ya tatu ni r = 10 cm. Step 2: Tumia formula ya mzingo. C = 2 r C = 2 × 3.14 × 10 cm Step 3: Hesabu mzingo. C = 6.28 × 10 cm C = 62.8 cm Mzingo wa duara c) ni 62.8 cm. Tuma swali linalofuata 📸
