The volume of a cylinder is pi*height*radius^2 = pi*5*(14/2)^2 = 769.69 ft^3. To get the total gallons multiply 769.69 ft^3 by 7.5gal/ft^3 to get 5772.6765 gallons or 5773 gallons rounded to nearest whole number.
The discriminant is b<span>²-4ac We can rewrite x</span>² = 4 to x<span>² + 0x - 4 = 0 So a = 1, b = 0, c = -4 </span>Δ = 0 - 4 * 1 * -4 Δ = 16 The answer is B
