Volume = 4/3*pi*r^3
As diameter = 6 inches
Radius = Diameter / 2
Radius = 6/ 2
Radius = 3 inches
Putting the value of r in the formula :
=4/3*pi*3^3
 =4/3*pi*27
= 36*pi
So according to above explanation,
B) V = 36 π cubic inches , is the correct answer.

A golf ball is hit from the ground with an initial velocity of 208 ft./s. assume the starting height of the ball is 0 feet. how

V125BC [204]

Check the picture below, it hits the ground at y = 0

thus

$\bf \qquad \textit{initial velocity}\\\\
\begin{array}{llll}
\qquad \textit{in feet}\\\\
h(t) = -16t^2+v_ot+h_o
\end{array} 
\quad 
\begin{cases}
v_o=\textit{initial velocity of the object}\\
h_o=\textit{initial height of the object}\\
h=\textit{height of the object at "t" seconds}\\
----------\\
v_o=208\\
h_o=0
\end{cases}$

$\bf h(t)=-16t^2+208t+0\implies h(t)=-16t^2+208t\impliedby 
\begin{array}{llll}
\textit{now let's}\\
make\\ h(t)=0
\end{array}
\\\\\\
0=-16t^2+208t\implies 0=t(208-16t)
\\\\\\
\begin{cases}
0=t\\
----------\\
0=208-16t\\
\qquad 16t=208\\
\qquad t=\frac{208}{16}
\end{cases}$

and I'm sure you know how much that is

it hits it at two points, as you notice in the picture, at 0 seconds, when it's first hit and goes up, and when it falls down.
