Question

Convert 72 degrees Celsius to Fahrenheit.

• A. \( 160.8^\circ \mathrm{F} \)
• B. \( 161.6^\circ \mathrm{F} \)
• C. \( 162.0^\circ \mathrm{F} \)
• D. \( 163.5^\circ \mathrm{F} \)

Hint:

Use the conversion formula \( \mathrm{F} = \left( \frac{9}{5} \times \mathrm{C} \right) + 32 \) for quick conversions from Celsius to Fahrenheit.

Answer 1

The Correct Option is B

Step 1: Recall the formula for Celsius to Fahrenheit conversion.
The conversion formula is given by: \[ \mathrm{F} = \left( \frac{9}{5} \times \mathrm{C} \right) + 32. \] Step 2: Substitute the given value of \( \mathrm{C} = 72 \).
\[ \mathrm{F} = \left( \frac{9}{5} \times 72 \right) + 32. \] Step 3: Perform the calculation.
First, calculate \( \frac{9}{5} \times 72 \): \[ \frac{9}{5} \times 72 = 129.6. \] Add 32 to this result: \[ \mathrm{F} = 129.6 + 32 = 161.6. \] Thus, \( 72^\circ \mathrm{C} = 161.6^\circ \mathrm{F} \).
