Answer:
SA = 31.714 km²
Step-by-step explanation:
SA = πr² + πrl
SA = 3.14(1)² + 3.14(1)(9.1)
SA = 3.14 + 28.574
SA = 31.714 km²
Temperature after 20 minutes is found by multiplying-2.5 by 20 since it goes down by 2.5 degrees for one minute. -2.5 * 20 = -50. Adding this to 180.3 will give the temperature 130.3 degrees.
