Answer:
D. 735.25 cubic inches.
Step-by-step explanation:
Well hello there! My name is Lunako, and I'm here to help you out.
<h2>What we need to do:</h2>
Firstly, do you remember the formula for finding the volume of the sphere? Yep, it's 4π(r³/3)! I'll substitute r for 5.6 -- which is 11.2 divided by 2, but you knew that already right? -- and π for 3.14 -- I'm doing that for relative ease.
4(3.14) * (5.6³/3) <em>{Firstly we need to need find the cube of 5.6. That would be 175.616. Let me show the work for that: 5.6 * 5.6 = 25 + 3 + 3 + 0.36 = 31.36; 31.36 * 5.6 = 150 + 5 + 1.5 + 0.3 + 18 + 0.6 + 0.18 + 0.036 = 155 + 1.8 + 18.6 + 0.216 = 156.8 + 18.816 = 175.616}</em>
4(3.14) * (175.616/3) <em>{Now divide 175.616 by 3 to get 58.5387 (rounded to 54 places).}</em>
4(3.14) * 58.5387 <em>{Now onto the left sides. 3.14 quadrupled is 12.56.}</em>
12.56 * 58.5387 <em>{Now for the last step: Multiplying 12.56 by 58.5387. The work for that is shown in the picture. You should get 735.246072.}</em>
735.246072 in³ <em>{While this is the answer, we need to round it to two decimal places, like in the answer choices. 6 is greater then 5, so round up to 735.25.}</em>
735.25 in³<em> </em><em>{And with that this problem is solved.}</em>
<h2>The Answer:</h2>
The volume of the sphere is 735.25 cubic inches, which is D.

Answer:
30. $<u>25.42</u>
31. $<u>21.48 </u>
32. $<u>23.06</u>
Step-by-step explanation:
30. 8.54+7.50+9.38 = 25.42
31. 6.99+5.99+8.50 = 21.48
32. 8.50+5.33+9.23 = 23.06
6x thats thats the answer
I can't see the multiple choice do u mind doing another pic :| sorry
Answer:
Step-by-step explanation:
b + 70 = 180 {Supplementary angles}
b = 180 - 70
b = 110
a +b = 180 {Linear pair}
a + 110 = 180
a = 180 - 110
a = 70
d + 60 = 180 {linear pair}
d = 180 - 60
d = 120
c + d + 60 = 360 {one point angle}
c + 120 + 60 = 360
c + 180 = 360
c = 360 - 180
c = 180
f + 60 = 180 {Supplementary angles}
f = 180 - 60
f = 120
