Answer:
7. 1583.36 cm³
8. 13,627.18 m³
Step-by-step explanation:
Volume of space consumed by the paper = volume of outer cylinder - volume of center cylinder
✔️Volume of Outer Cylinder:
Volume = πr²h
r = ½(12) = 6 cm
h = 14 cm
Volume = π*6²*14
Volume = 1583.36 cm³
✔️Volume of center cylinder:
Volume = πr²h
r = ½(4) = 2 cm
h = 14 cm
Volume = π*2²*14
Volume = 175.93 cm³
✅Volume of space of the toilet paper = 1583.36 - 175.93 = 1583.36 cm³
8. Volume of the solid = volume of the cone + volume of the cylinder
✔️Volume of the cone = ⅓πr²h:
r = 13 m
h = 14 m
V = ⅓*π*13²*14
V = 2,477.67 m³
✔️Volume of the cylinder = πr²h
r = 13 m
h = 21 m
V = π*13²*21
V = 11,149.51 m³
✅Volume of the solid = 2,477.67 + 11,149.51 = 13,627.18 m³

Hello!</h2>
The answer is: The square root of 72 is 8.5
<h2>
Why?</h2>
To solve this problem we need to remember how to operate with square roots.
So, we are asked to estimate the square root of 72, to find the problem, we need to factor 72, and then, apply the square root property.
Now, since 36 is a perfect square (it can be obtained by squaring a whole number), we have:
Then, we have that 8.48 rounded to the nearest tenth is equal to 8.5.
Hence, we have that , the square root of 72 is equal to 8.5.
Have a nice day!
Answer:
2/8, 3/8, 4/8, 5/8, 7/8. If there are more numbers I apologize, I see 2 boxes that say "obj" instead.
