9,42 cm 4. 50,27 cm 5. 21.99 4a. Find the circumference (in cm) of each circle. 34,56 cm 3. 3.14 cm 3. 78.54 cm 4.
380.13 1c. This also means the circumference and area of a circle have a weird but interesting relationship, like …
Find the area and circumference of each circle. 1-10 90 80 70 60 50 40 30 20 10 0 1) 30 2) 1 3) 25 4) 14 5) 14 6) 15 7) 13.5 8) 3.5 9) 11 10) 24 1. 47.12 cm 7. 69.12 cm 10. And since the diameter is just double the radius, we can re-rewrite it as C = 2πr. Answer Key 1-10 95 90 85 80 75 70 65 60 55 50 11-20 45 40 35 30 25 20 15 10 5 0 1) 11 2) 10 3) 7 4) 14.5 5) 30 6) 25 7) 28 8) 9.5 9) 21 10) 3 1a. 69.12 2a. 572,56 cm 2 1c. 38.48 3c.
That means we can rearrange this ratio to find the circumference in terms of the diameter: C = πd.
