Answer: B
Step-by-step explanation: You make the values in the parentheses equal to zero.
(X + 3) = 0
X = -3
A is wrong because the root would be 3, not negative 3. C is wrong because 3 isn’t guaranteed to be a root. D is wrong because -3 is a real solution.
The formula for volume of a sphere is : V= 4/3 * PI * r^3
r = 1/2 the diameter: 14/2 = 7 feet
Volume = 4/3 * 3.14 * 7^3
Volume = 1,436 cubic feet.
Well it looks really simple I'm gonna go with 5
