To convert degrees into radians, we use the conversion factor that π radians is equal to 180 degrees. To convert 70 degrees to radians, we can set up the following equation:
Radians = Degrees × (π / 180)
Plugging in our value of 70 degrees, we have:
Radians = 70 × (π / 180)
Now, we can simplify this fraction:
Radians = (70π) / 180
This can be reduced by dividing both 70 and 180 by 10:
Radians = (7π) / 18
So, the exact fraction that represents 70 degrees in radians is (7π)/18.
