Area of Circle = πr^2
Since we know that r=6.3:
π(6.3)^2=39.69 π=124.690
So, the area would be 124.690.

Answer # 1 and answer #4
Step-by-step explanation:
If line XY is a bisector, it divided the line YW in half, therefore making ZY equal to ZW
Euclids 1st book proposition 13 states that a line standing on another line makes 2 right angles. therefore <YZW is a right angle because that angle plus <WZX must be equal to 180 and line YW splits the angles in half
