The angle θ is an integer (e. g. 0, ±1, ±2, ...) when measured in radians. Give the radian measure of the angle. (It helps to remember π ≈ 3.)

In the field of thermodynamics, rankine is the unit used to measure temperature. one can convert temperature from celsius into rankine using the formula , what is the temperature in celsius corresponding to r degrees rankine? a. 9/5(c - 273) b. 9/5(c + 273) c. 5/9( c - 273) d. 5/9( c + 273)
