A circular tire of 1.2 m in diameter must be attached to a steel rim of the same diameter. In order to be able to adjust it, you want to heat up the tire until its radius is 5 mm greater than that of the rim. Knowing that the ambient temperature is 20ā°C and its coefficient of linear expansion is 4.8x10^-4ā°C^-1, calculate the temperature in ā°C to which the tire must be heated to meet the aforementioned conditions.
