PLEASE HELP! Will mark Brainliest!

Answer 1

Circle A would make more sense (I'm not exactly sure) because it shows the entire circle (if you know what I mean).

Answer 2

Area A = 10^2(π/180x90 - sin90)
Area A = 28.54

Area B = 12^2(π/180x60 - sin60)
Area B = 13.04

segments CED has a greater area

so answer
Circle A: radius = 10m, m∠CAD = 90°
