Answer: 25.12 m.
Step-by-step explanation: To find the circumference of a circle, you can use the formula C = πd or C = 2πr, where C represents the circumference, π is a constant approximately equal to 3.14, d is the diameter, and r is the radius of the circle. In this case, we are given the radius of the circle as 4 m. To find the circumference, we can use the formula C = 2πr. Plugging in the given value, we get: C = 2π(4) Simplifying, we have: C = 8π Now, since we are asked to use π = 3.14, we can substitute this value into the equation: C = 8(3.14) Calculating this expression, we find: C ≈ 25.12 m Therefore, the circumference of the circle with a radius of 4 m is approximately 25.12 m.
