Need help with this quiz please and thank you

Answer:
Step-by-step explanation:
1. ¹/₃ × π × r² × l:so 33.9.29cm³
2. π × r² × l:so π x 2² x 3.5=43.98ft³
3.¹/₃ × π × r² × l, to get the radius from diameter you divide the diameter by 2 so it would look like: ¹/₃ × π x 4² x 12= 201.06in³
4.352cm³
5. cone: 1/3 πr²h
Cylinder: πr²h
cone : 33 Cylinder = 3 x 33 = 99 in³
