Answer:
Option B is correct.
Step-by-step explanation:
Diagram of given scenario shown below.
Given that,
Diameter of cylinder is
.
Height of cylinder is
.
So, Radius of cylinder is ![= \frac{4}{2}=2\ mm](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B4%7D%7B2%7D%3D2%5C%20mm)
Volume of cylinder =
{where,
,
is the radius
of cylinder and
is height of cylinder}
Substituting the values we get,
Volume of cylinder ![=\pi \times (2)^{2}\times 8](https://tex.z-dn.net/?f=%3D%5Cpi%20%5Ctimes%20%282%29%5E%7B2%7D%5Ctimes%208)
![=3.14 \times 32\\=100.48\ mm^{3}](https://tex.z-dn.net/?f=%3D3.14%20%5Ctimes%2032%5C%5C%3D100.48%5C%20mm%5E%7B3%7D)
Therefore, Required volume of Cylinder rounding it to the nearest tenth ≈
.
Hence, option B is correct.
Answer:
y = 1.705882353
Step-by-step explanation:Combine like terms: 20 + 9 = 29
29 + -10y + -7y = 0
Combine like terms: -10y + -7y = -17y
29 + -17y = 0
Solving
29 + -17y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-29' to each side of the equation.
29 + -29 + -17y = 0 + -29
Combine like terms: 29 + -29 = 0
0 + -17y = 0 + -29
-17y = 0 + -29
Combine like terms: 0 + -29 = -29
-17y = -29
Divide each side by '-17'.
y = 1.705882353
Simplifying
y = 1.705882353
99 16/25 or 2491/25
100-9/25= 99.64
99.64 as a mixed number is 99 16/25 or 2491/25 as an improper fraction
Answer:
$63
Step-by-step explanation:
70 x 10% = 7
70 - 7 = 63
