<span>The theoretical probability of spinning any one of the five colors is 20%.
The theoretical probability of spinning green is equal to the experimental probability of spinning green.
If Yuri spins the spinner 600 more times and records results, the experimental probability of spinning orange will get closer to the theoretical probability of spinning orange.</span>
Answer:1.3
Step-by-step explanation:

The surface of interest can be parameterized by

with

and

.
The area of the surface

is given by the surface integral

We have

so the area is given by the double integral
