Volume of a sphere with radius of 70 feet is:
![V = \frac{4}{3} * \pi * r^{3}](https://tex.z-dn.net/?f=V%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%2A%20%5Cpi%20%2A%20r%5E%7B3%7D%20)
where r is that radius
Because we need quarter sized tank of that radius we need to divide formula for volume by 4
Than we get:
![V = \frac{1}{3} * \pi * r^{3}](https://tex.z-dn.net/?f=V%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20%2A%20%5Cpi%20%2A%20r%5E%7B3%7D%20)
V = 359188,76
Rounded:
V = 359189
You can rewrite that as:
a^2-4ab+6ab-24b^2 then factor 1st and 2nd pair of terms.
a(a-4b)+6b(a-4b) so you have
(a+6b)(a-4b)
