Answer:

Step-by-step explanation:





Based on the given details, the assumption that must be made about the sun rays if using the method of determining the circumference of a large sphere is that, the rays it emits are of a certain angle from one another and these rays would travel in parallel. These rays are not touching, therefore, its angles are the same. Hope this answer helps.
If its diameter is 443 square inches, then its circumference is:
443 π square inches, as C=πd.
