Answer: Volume = 97.6
Step-by-step explanation:
Volume of the cone first
V = 1/3 h π r²
<u>h = 0.7</u>
<u>r = 2</u>
V = 1/3 × 0.7 × 2² × 3.14
V = 1/3 × 0.7 × 4 × 3.14
V = 1/3 × 8.792
V = 2.93
Then find the volume of the cylinder if the cone was there.
V = π r² h
<u>r = 2</u>
<u>h = 8 </u>
V = 3.14 × 2² × 8
V = 3.14 × 4 × 8
V = 3.14 × 32
V = 100.48
Now you subtract the volume of the cone from the cylinder.
100.48 - 2.93 = 97.55
Rounded to the nearest tenth is 97.6
Hope this was helpful, I know it is a lot to look at but I tried my best.
Also, can I get brainliest? I worked really hard on this.

Answer:
y = 4x - 1
Step-by-step explanation:
The line has a slope of 4.
And passes through the point (1,3)
Taking another point (x,y) on the line;
= 4
y - 3 = 4x - 4
y = 4x - 4 + 3
y = 4x - 1
Answer: n = 4
Step-by-step explanation:
The given expression is
2n+4=12
We want to solve for n. The first step is to make 2n stand alone on the left hand side of the equation. This is achieved by subtracting 4 from the left hand side and the right hand side of the equation. It becomes
2n + 4 - 4=12 - 4
2n = 8
The next step is to divide the left hand side and the right hand side of the equation by 2. It becomes
2n/2 = 8/2
n = 4
