What we need to know: The formula for the volume of a cone is: ![V=\pi r^{2} \frac{h}{3}](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7D%20%5Cfrac%7Bh%7D%7B3%7D)
So we are solving for V
Step-by-step explanation:
1) Radius is half of diameter r=30/2 thus, your radius is 15
2) you then have all your variables so you can start plugging values into your equation:
r=15 h=60
![V=\pi 15^{2} \frac{60}{3} \\V=\pi (225)*(20)\\V=\pi(4500) \\V= 4500\pi](https://tex.z-dn.net/?f=V%3D%5Cpi%2015%5E%7B2%7D%20%5Cfrac%7B60%7D%7B3%7D%20%5C%5CV%3D%5Cpi%20%28225%29%2A%2820%29%5C%5CV%3D%5Cpi%284500%29%20%5C%5CV%3D%204500%5Cpi)
This would be your exact answer but if you are solving for a rounded answer it would be

1. Construct a circle of arbitrary radius (r₁) with center at point P (blue circle)
2. Mark the points of intersection of the circle with the line AB (points E and D)
3. Construct two circles of identical radii (r₂) with centers at points E and D (green and red circles). Notice: r₂ > r₁
4. Draw a segment through the intersection points of the green and red circles.
Answer:
8
Step-by-step explanation:
Remember: Keep, Change, Flip
keep 4 the same, change the division to multiplication, and flip the fraction from 1/2 to 2
4 x 2=8
