Can sumone help me with this question

Determine the volume of a cylinder bucket if the diameter is 8.5 in. and the height is 11.5 in.

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

State if the two triangles are congruent. if they are, state how you know?
