3- A surveyor uses a steel measuring tape that is exactly 15.000 m long at a temperature of 30°C. The markings on the tape are calibrated for this temperature. (a) What is the length of the tape when the temperature is 35°C? (b) When it is 45°C, the surveyor uses the tape to measure a distance The value that she reads off the tape is 40.794 m. What is the actual distance?
