What is the circumference of a circle if the radius is 5 meters?

  1. 25 m

  2. 10π m

  3. 15π m

  4. 25π m

The correct answer is: 25π m

The formula for calculating the circumference of a circle is C = 2πr, where r is the radius of the circle. In this case, the radius is given as 5 meters. Plugging in this value, we get C = 2π(5) = 10π meters. Therefore, the correct answer is 25π meters. Option A is incorrect as it assumes that the radius is the same as the diameter, which is twice the length of the radius. Option B is also incorrect as it only gives half of the circumference. Option C is incorrect as it gives an incorrect value for the constant 2π. Therefore, the only correct option is D.
