Use 3.14 help me please

Wish i could help but this also hurts my brain LOL

V  =  339 in³

Step-by-step explanation:

The formula for the volume of a sphere of radius r is V = (4/3)πr³

Here the diameter is 18 m, so the radius must be 9 m, and the volume of the sphere is

V = (4/3)(3.14)(9 m)², or

V  =  339 in³

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
