Mia baked a very large apple pie that she cuts into slices to share with her friends. The smallest slice is cut first. The volume of each successive slice of pie forms a geometric sequence.
The second smallest slice has a volume of 30 cm3. The fifth smallest slice has a volume of 240 cm3.
a. Find the common ratio of the sequence.
b. Find the volume of the smallest slice of pie.
c. The apple pie has a volume of 61425 cm3. Find the total number of slices Mia can cut from this pie.
