You would add up all of the sides by combining like terms. Let me know if you want the answers for it.
Answer:
12. 524 in³ (3 sig. fig.) 13. 2000 cm³ (3 sig. fig.)
Step-by-step explanation:
12. Volume of sphere = (4/3)πr³
= 500/3π
= 524 in³ (3 sig. fig.)
13. Volume of cylinder = πr²h
= 7²π(13)
= 637π
= 2000 cm³ (3 sig. fig.)
The height of the cone is 8.59
7/12 = 0.84
0.84/36 = 0.0233·
