Please I want help I want a correct answer

Mathematics
1 answer:
nikdorinn [45]3 years ago
5 0

Answer:

12.1\pi, 7.4\pi

Step-by-step explanation:

First, we all know the formula its 2\piR however here we see the diameter to find R we have to divide: 12.1 divided by 2=6.05 but for me thats really useless because in the end you still have to multiply it by 2 so to find the circumference just find the diameter and add a pie beside it so the answer would be 12.1\pi for the others do the same thing. (pls give me brainliest or something)
