I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.
Answer:
A. 69.12 in.³
Step-by-step explanation:
Volume of the crayon balloon = volume of the cone + volume of the cylinder
= ⅓πr²h + πr²h
✔️Volume of Cone = ⅓πr²h
r = ½(2) = 1 in.
h = 3 in.
Volume of cone = ⅓*π*1²*3 = 3.142 in.³
✔️Volume of Cylinder = πr²h
r = ½(2) = 1 in.
h = 21 in.
Volume of Cylinder = π*1²*21 = 65.97 in.³
✅Volume of the crayon balloon = 3.14 + 65.973 = 69.115
= 69.12 in.³ (nearest hundredth)
Looks to me like you have the right answer...
