31. Make Sense and Persevere The bottom of a hemispherical cake has diameter 8 in.
8 in.
a. If the cake is sliced horizontally in half so each
piece has the same height would the top half
fit on a plate with diameter 6 in.? Explain.
b. If the cake is sliced horizontally in thirds so
each piece has the same height, would the
top third fit on a plate with diameter 5 in.?

the inequality is:

250c+180g≥950
