Volume formula of a sphere:


r³
given:
r = 3
V =


(3)³
V =

× 27

V = 36

units³ (in terms of

)
V = 113.097 units³ ≈ 113.1 units³
Helen should of put 0 first, because if you're gonna divide, you need to put the product first, then one of the factoes.
So instead it should be 0÷(-7)=0
X^2+12x=0
(ax^2+bx)=0
(b/2)^2=(12/2)^2=(6)^2=36
x^2+12x+36=(x+6)^2
Got me there but i think its 325500
