8th grade geometry part 3, please explain the steps :)))

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.
