Construct npda's that accept the following languages on σ = {a, b,c): (a) l = {a"pin : n > 0} (c) l = {a"bmcn+m : n > 0, m2 0} (e) l = {a"b"c": n > 0} nb (w) + 1} (g) l = {w : na (to) o l (i) l-w : na (w) + nb (w) = ne(w)) ). , = {w : na (w) = 2n6 (w)

Ithink the answer is b. hope this .

Just trying to get some points : p sorry bro

Hypothesis: volumes of both figures are equal.the volume of  figure 1 is: .the volume of figure 2 is: .since , you can conclude that and . so, .volumes of figures are equal only when an angle in the basis is right (then figures will be the same), in another cases volume of figure 1 is less than volume of figure 2.the hypothesis was not correct in all cases.
