2 answers:
Answer:
A. 31.4 in.
Step-by-step explanation:
Formula for the circumference:
C = dπ (d = 2r)
Therefore:
C = 10π
C = 10 · 3.14
C = 31.4 in.
Answer:
A: 31.4 in
Step-by-step explanation:
Use the equation C = 2πr to solve your problem.
Since you are given the radius <em>r </em>you only need to plug in 5 in. to r and calculate it on the calc. When you multiply everything together you should get 31.4 in.
