To convert radians into degrees, we use the formula: degrees = radians * (180 / pi).
We can now substitute the given values in the formula above.
We are given that the radian value is 3.12 and the value of Pi you should use is 3.14.
Replace radians and pi in the formula with 3.12 and 3.14 respectively:
degrees = 3.12 * (180 / 3.14)
After performing the calculation, you will find that the degree value is approximately 178.85350318471336.
This question wants the answer rounded to the nearest tenth.
Round up the obtained degree value to the nearest tenth which is 178.9.
So, if you convert 3.12 radians to degrees, you get approximately 178.9 degrees when rounded to the nearest tenth decimal place.
