Answer:
7. 75.36 inches
8. 21 inches
9. 13 inches
Step-by-step explanation:
7. <em>Circumference = π × d</em>
The diameter would be two times the radius, or 2 × 12 = 24. So, circumference would be 3.14 × 24 = 75.36 inches.
8. <em>Circumference = π × d</em>
If we move variables around, <em>d = Circumference / π</em>
So, d = 65.94 / 3.14 = 21 inches.
9. To do this, let's figure out the diameter: <em>d = Circumference / π</em>
d = 81.64 / 3.14 = 26. Now the diameter is two times the radius, so to get the length of the radius, we must divide the diameter in half. 26 / 2 = 13 inches.
