A<b+c so if b=15 and c=40 then
a<15+40
a<45
so a cant possibly be d. 50ft
i think its c.

A proposition of the form “if p then q” or “p implies q”, represented “p → q” is called a conditional proposition. ... The proposition p is called hypothesis or antecedent, and the proposition q is the conclusion or consequent. Note that p → q is true always except when p is true and q is false
Well formula is pie times radius squared times height over 3
Plug it all in and your answer is 20.94
706.86 is the answer for the area
