Answer:
The approximate temperature of the preheated oven is 204 °C.
Step-by-step explanation:
Here, the given temperature in Fahrenheit = 400 °F
Let us assume the given temperature in Celsius = C
Now, the relation between the two measure of temperature is given as:
[tex]F =( \frac{9}{5} )C + 32[/tex]
According to the question:
[tex]400 =( \frac{9}{5})C + 32 \\\implies ( \frac{9}{5})C = 400 - 32 = 368\\or, C = 368 \times\frac{5}{9} =204.4[/tex]
Or, C = 204.4°C
Hence, the approximate temperature of the preheated oven is 204 °C.
