Explanation:

Step1: Write the conversion formula

The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{5}{9}(F - 32)$.

Step2: Substitute the given value

Substitute $F = 43.2$ into the formula: $C=\frac{5}{9}(43.2 - 32)$.
First, calculate the value inside the parentheses: $43.2-32 = 11.2$.
Then, calculate $C=\frac{5}{9}\times11.2$.
$C=\frac{56}{9}\approx6.222\cdots$.

Step3: Round to significant figures

The input value $43.2$ has 3 significant - figures. So, rounding $6.222\cdots$ to 3 significant - figures gives $6.22$.

Answer:

$6.22$
