Question

Find the circumference of a circle if the radius is 2 inches.

Answer 1

Answer:

12.56

Step-by-step explanation:

Since the C = pi*D and radius is half the diameter you have to do 2*2=4 then you have to do 3.14*4 which then gives you your final answer of 12.56

Answer 2

Answer:

12.566368 units

Step-by-step explanation:

2(pi)r = C

2(pi)(2) = C

4(pi) = C

4(3.141592) = C

12.566368 = C
