The temperature of a healthy human body is `98.6^(@)F`. His temperature in degree centigrade is

Options

A. 38
B. 36
C. 37
D. 39

Answer

To convert the temperature from Fahrenheit to Celsius, we can use the formula:

\[ C = \frac{5}{9} (F - 32) \]

where \( C \) is the temperature in degrees Celsius and \( F \) is the temperature in degrees Fahrenheit.

### Step-by-Step Solution:

1. **Identify the given temperature in Fahrenheit:**
\[ F = 98.6^\circ F \]

2. **Substitute the value of \( F \) into the conversion formula:**
\[ C = \frac{5}{9} (98.6 - 32) \]

3. **Calculate \( 98.6 - 32 \):**
\[ 98.6 - 32 = 66.6 \]

4. **Substitute this value back into the equation:**
\[ C = \frac{5}{9} \times 66.6 \]

5. **Multiply \( 66.6 \) by \( 5 \):**
\[ 66.6 \times 5 = 333 \]

6. **Now divide \( 333 \) by \( 9 \):**
\[ C = \frac{333}{9} = 37 \]

7. **Final result:**
\[ C \approx 37^\circ C \]

### Conclusion:
The temperature of a healthy human body in degrees Celsius is approximately \( 37^\circ C \).
