Step-by-step explanation:
1. 0.030303......*100
=3.0303....



<h3>This is the explination</h3>
2.

Multiplying by 1 keeps it the same. A number greater than 1 would be an increase and a number below 1 would be a decrease.
The decrease is 2.7% which is written as 0.027 as a decimal.
Subtract that from 1:
1 - 0.027 = 0.973
The multiplier would be 0.973
Check the picture below.
since we know the endpoints of the diameter of the circle, then we can simply get the midpoint of those endpoints and that'd be the center,
