Answer:
For the first two problems, there is nothing that I should solve for, lmk and I will solve it again. For now, I just solved for the sector.
Step-by-step explanation:
1. s=(7pi)/2
2. s=14pi/5
3. 240
4. s=((pi)r(<APC))/180
the circumference of the circle is 20pi and ABC is 16pi so the minor arc AC is 4pi=s
4pi=(pi)(10)(x)/180
x=72
Hope that helps :)
