A circle has a diameter of 10 cm. What is its circumference? (2022)

Step 1: Understand that the diameter of the circle is given as 10 cm.
Step 2: Recall the formula for the circumference of a circle, which is Circumference = π * diameter.
Step 3: Substitute the diameter into the formula: Circumference = π * 10 cm.
Step 4: Use the approximate value of π (pi), which is about 3.14.
Step 5: Calculate the circumference: Circumference = 3.14 * 10 cm.
Step 6: Multiply 3.14 by 10 to get 31.4 cm.
Step 7: Conclude that the circumference of the circle is 31.4 cm.

Circumference of a Circle – The circumference of a circle can be calculated using the formula C = πd, where d is the diameter.
