Answer : The correct option is, (B) [tex]204^oC[/tex]
Step-by-step explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:
[tex]^oC=\frac{5}{9}\times (^oF-32)[/tex]
where,
[tex]^oF[/tex] = temperature in Fahrenheit
[tex]^oC[/tex] = temperature in centigrade
Given:
Temperature in Fahrenheit = [tex]400^oF[/tex]
Now put the value of Fahrenheit in above expression, we get the value of temperature in Celsius degrees.
[tex]^oC=\frac{5}{9}\times (400-32)[/tex]
[tex]^oC=204.4\approx 204[/tex]
Therefore, the approximate temperature of the preheated oven in Celsius degrees is, [tex]204^oC[/tex]
