Ka for weak acids is ---> Ka= (X)²/ (initial- X)
initial= 0.0400 M
to find X, you can find the H concentration using pH
[H+]= 10^-pH
[H+]= 10^-1.80= 0.016 which is X
ka = (0.016)²/ (0.0400 - 0.016) = 0.011
The answer is c, because the top of the hemisphere and the bottom of the hemisphere make up the equator. Hope this helps and I hope you mark me brainliest!
