Question

Help, with an explanation please

Answer 1

`c = 2 * 8 * 3.14 = 50.24`

Answer 2

50.24 in

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
