Answer:

Step-by-step explanation:
The formula of a volume of a cone:

<em>r</em><em> - radius</em>
<em>H</em><em> - height</em>
We have the diameter <em>2r = 10in → r = 5in</em>, and the height <em>H = 28in.</em>
Substitute:


the area of land is 4.9*6.2*0.225=6.8355m^3 (6.8355m^3/0.87≈7.85 yes you have enough
Answer:
f(x) = 4x² + 9x - 28
Step-by-step explanation:
Create the polynomial by multiplying (4x - 7) and (x + 4) together:
f(x) = 4x² + 16x - 7x - 28, or
f(x) = 4x² + 9x - 28
