Here are the circumferences for all the circles: The formula for the circumference of a circle is C = 2 r (where r is the radius) or C = d (where d is the diameter). We will use ≈ (22)/(7). Step 1: Calculate the circumference for circles 1, 2, and 3. 1. Given radius r = 21 cm. C = 2 r = 2 × (22)/(7) × 21 cm C = 2 × 22 × 3 cm C = 132 cm 2. Given diameter d = 28 cm. C = d = (22)/(7) × 28 cm C = 22 × 4 cm C = 88 cm 3. Given radius r = 7 cm. C = 2 r = 2 × (22)/(7) × 7 cm C = 2 × 22 cm C = 44 cm Step 2: Calculate the circumference for circles 4, 5, and 6. 4. Given diameter d = 15 cm. C = d = (22)/(7) × 15 cm C = (330)/(7) cm C = 47(1)/(7) cm 5. Given radius r = 11 cm. C = 2 r = 2 × (22)/(7) × 11 cm C = (484)/(7) cm C = 69(1)/(7) cm 6. Given diameter d = 49 cm. C = d = (22)/(7) × 49 cm C = 22 × 7 cm C = 154 cm What's next?
