To find the diameter of a circle, we need to know its circumference. The circumference of a circle is the distance around its outer edge.
Given that the circumference of the circle is 66 cm, we can find the diameter using the formula:
Circumference = π × Diameter
where π is a mathematical constant approximately equal to 3.14.
Let's solve this step by step:
Step 1: Write down the given information:
Circumference = 66 cm
Step 2: Substitute the known values into the formula:
66 cm = 3.14 × Diameter
Step 3: Solve for the diameter:
Diameter = 66 cm / 3.14
Step 4: Calculate the diameter:
Diameter ≈ 21 cm
Therefore, the diameter of the circle is approximately 21 cm.
Explanation:
- The diameter of a circle is a straight line passing through the center of the circle and connecting two points on its circumference.
- The circumference of a circle is the distance around its outer edge.
- To find the diameter, we use the formula Circumference = π × Diameter.
- By rearranging the formula, we can solve for the diameter.
- Substituting the given circumference of 66 cm into the formula, we can calculate the diameter.
