pentagon [3]

Answer:

 1331π cm³

Explanation:

\sf V_{cylinder} = \pi (radius)^2 (height)

Here given:

  • radius: 11 cm
  • height: 11 cm

Hence find volume:

\sf \rightarrow\pi (11)^2 (11)

\sf \rightarrow 121\pi ( (11)

\sf \rightarrow 1331\pi \quad \approx \:\:\ 4181.46 \ cm^3

lisabon 2012 [21]

Answer:

The first listed equation is the correct equation to solve

The correct answer is: t = 5 seconds

Step-by-step explanation:

Let me mention first that there is an error in the statement that the gravitational pull of the Earth is 16 ft/s^2. It is in fact 32 ft/s^2, and the actual equation uses half of the acceleration multiplied by the square of the variable time, so it gives as final expression :

y(t)=-16\,t^2+ 0 \,t +400

and we want to find the value/s for "t" that make this equation equal zero (when it reaches the ground and the object just touches the ground. This makes the equation we want to solve:

0=-16\,t^2+ 0 \,t +400\\16\,t^2+0\,t -400=0

which solving for "t" becomes:

16\,t^2-400 =0\\16\,t^2=400\\t^2=\frac{400}{16} \\t^2=25\\t= +/- 5\,\,sec

So we adopt the positive answer (positive time) since the negative value has no physical meaning for this problem.

That is: t = 5 seconds
