Answer:
1, 3, and 4 are correct
Step-by-step explanation:
- We know that to find the radius, we divide the diameter by 2, so the first one is correct.
- We know that the second one is incorrect because we just said that we would divide the diameter by 2 for the radius, so we would multiply the radius by 2 to find the diameter.
- The third statement is correct because the circumference is approximately 3 times bigger than the diameter.
- The fourth statement is correct because the circumference is equal to pi times 2 times the radius.
If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
