Question

convert 91.2°c to degrees fahrenheit.
round your answer to the correct number of significant figures.
°f

Explanation:

Step1: Recall conversion formula

$F = \frac{9}{5}C+32$

Step2: Substitute Celsius value

$F=\frac{9}{5}\times91.2 + 32$
$F = 1.8\times91.2+32$
$F = 164.16+32$
$F = 196.16$

Step3: Round to significant figures

The input 91.2 has 3 significant figures. Rounding 196.16 to 3 significant figures gives 196.

Answer:

196°F
