Step-by-step solution

4 steps

To find the circumference of a circle, we use the formula that relates circumference to diameter.

Problem: The diameter of a circle is 5 cm5 \text{ cm}. Find the circumference. (Use π=3.14\pi = 3.14)

  1. Identify the given values.

    The diameter (dd) is 5 cm5 \text{ cm}.
    The value of π\pi is given as 3.14.

  2. Recall the formula for the circumference (CC) of a circle using its diameter.

    C=π×dC = \pi \times d

  3. Substitute the given values into the formula.

    C=3.14×5 cmC = 3.14 \times 5 \text{ cm}

  4. Perform the multiplication.

    C=15.70 cmC = 15.70 \text{ cm}

    The circumference of the circle is 15.70 cm15.70 \text{ cm}.
