Solution
Step 1 ：We are given a circle with radius 5 m. We are asked to find the circumference and the area of the circle using the value 3.14 for π.
Step 2 ：The formula for the circumference of a circle is \(C = 2\pi r\), where \(r\) is the radius of the circle.
Step 3 ：Substituting the given values into the formula, we get \(C = 2 * 3.14 * 5\).
Step 4 ：Calculating the above expression, we find that the circumference \(C\) is approximately 31.42 m.
Step 5 ：The formula for the area of a circle is \(A = \pi r^2\), where \(r\) is the radius of the circle.
Step 6 ：Substituting the given values into the formula, we get \(A = 3.14 * 5^2\).
Step 7 ：Calculating the above expression, we find that the area \(A\) is approximately 78.54 m².
Step 8 ：Final Answer: The circumference of the circle is \(\boxed{31.42 \, \text{m}}\) and the area of the circle is \(\boxed{78.54 \, \text{m}^2}\).
