4/3 * pi * radius^3 is the formula for volume of a sphere.
Answer:
2 or less packs
Step-by-step explanation:
15.99 + 1.99g < 20.00 where g is the number of packs of gum
Subtract 15.99 from each side
15.99 + 1.99g - 15.99 < 20.00-15.99
1.99g < 4.01
Divide by 1.99
1.99g/1.99 < 4.01/1.99
g < 2.015075377
Harold must buy whole packs so g =2 or less
So the formula is 2pi(r)(h)+2(pi)(r^2)
2(3.14)(40)(17)+2(pi)(40^2)
so then multiply and add it up and you get
about 14,325 1/3 or 14,325.34
