answer:
50.24 in
step-by-step explanation:
- the question is asking us to find the circumference
- the formula is given: C = 2πr
- all we have to do is plug in the info we know or get
C = 2πr
C = 2(3.14)(8)
- the diagram given us the radius since the line is half only — 8
- we have to use the given pi value — 3.14
- now solve the equation
C = 2(3.14)(8)
C = 50.24 in
