We can get the circumference of any circle in terms of the radius with this formula. C = 2

r.
Where r is the radius of the circle.
And we will use 3.14 for

.
Plug in all the values.
C = 2 * 3.14 * 2
C = 12.56
So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.
Answer:
Question 4: 20 + 6 + 6 + 12 + 16 = 60 
Question 5: 144 + 90 + 90 + 48 + 48 = 420 
Question 6: 78.28 + 78.28 + 88.58 + 27.09 + 27.09 = 299.32
