Circumference of a circle of diameter 5 cm is

Options

A. 3.14 cm
B. 31.4 cm
C. 15.7 cm
D. 1.57 cm

Answer

To find the circumference of a circle with a diameter of 5 cm, we can follow these steps:

### Step 1: Understand the formula for circumference
The formula for the circumference (C) of a circle is given by:
\[ C = \pi \times d \]
where \( d \) is the diameter of the circle.

### Step 2: Identify the diameter
In this problem, the diameter \( d \) is given as 5 cm.

### Step 3: Substitute the diameter into the formula
Now, we can substitute the value of the diameter into the formula:
\[ C = \pi \times 5 \]

### Step 4: Use the approximate value of π
For calculations, we can use the approximate value of π as 3.14. Therefore:
\[ C = 3.14 \times 5 \]

### Step 5: Perform the multiplication
Now, we multiply:
\[ C = 3.14 \times 5 = 15.7 \text{ cm} \]

### Final Answer
Thus, the circumference of the circle with a diameter of 5 cm is:
\[ C = 15.7 \text{ cm} \]
