Answer:
The formulas for converting between degree Celsius and degree Fahrenheit are:
°F = (°C * 9/5) + 32
°C = (°F - 32) * 5/9
To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations.
°C = (°C * 9/5) + 32
°C - (°C * 9/5) = 32
-4/5 * °C = 32
°C = -32 * 5/4
°C = -40
°F = (°F * 9/5) + 32
°F - (°F * 9/5) = 32
-4/5 * °F = 32
°F = -32 * 5/4
°F = -40
So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees
Have a nice day!!!

Answer:
Step-by-step explanation:
volume of cylinder = πr²h
πr²h = 127.23 cubic inches
3.14 * 3 * 3 * h = 127.23
h = 127.23 / 3*3*3.14
=127.23 * 100 /3*3*3.14*100
=12723/ 3*3*314
= 4241 / 3*314
=4241/ 942
=4.502 inches
h = 4.5 inches
