The surface area would be 166.
Answer:
you have to use the Pythagorean theorem. a^2 + b^2= c^2
72^2 + b^2 = 75^2
5184 + b^2 = 5625 (subtract 5184 from both sides)
b^2= 441 (find the square root of each side)
b= 21
If you would like to know what was the temperature after the increase, you can calculate this using the following step:
the beginning temperature: -9
increased: 37
the temperature after the increase: -9 + 37 = 28oF
The temperature after the increase was 28oF.
104 = 10,000 x 1.33 = 13,300
