3 inches diameter mean 1,5 in the radius
the height is 6,5 in.
volume of a cylinder = area of base time height
V= pir^2 *h
V = 3,14*1,5^2 *6,5
V = 45,92 in^3

Answer:
<em>approximately 52.752 or 16.8 </em>
<em />
Step-by-step explanation:
- First find the radius
a) we know the diameter so we can use the formula r=d/2 to solve for the radius
b)16.8/2 =8.4
2. Then we substitute into the equation
a)2r
b)2(8.4)
c)52.752 or 16.8
The general approach to this is to write the (x, y) coordinates of the trajectory's peak in terms of the sine and cosine of the launch angle α. Then use a trig identity (sin(2α)² + cos(2α)² = 1) to eliminate the dependence on α.
You should get
t = v₀sin(α)/g
x = v₀²sin(2α)/(2g)
y = v₀²(1-cos(2α))/(4g)
Solve each of the latter two equations for the trig function, then substitute those expressions into the trig identity above. Divide by the coefficient of x² and rearrange to get the expression shown.
