Step-by-step explanation:
I got this answer by making a variable, x, for the number of bananas you are buying. You can use this expression for whatever number of bananas you want and it will work.
12.3 - 7.9x

12.3 - 1.4x - 6.5=
a
because
Volume of the cone:
V = 3.14 x 3^2 x 9/3 = 84.78
Volume of half sphere on top of cone:
V = (4/3 x 3.14 x 3^3 )/2 = 56.52
Total volume = 56.52 + 84.78 = 141.3 cm^3
Hey there!
