Answer:
916.1 cm^3
Step-by-step explanation:
1) find the radius of the cylinder:
radius = dimater / 2 = 7,3 / 2 = 3.65 cm
2) find the base area of the cylinder:
base area = radius^2 x 3.14 = 3.65^2 x 3.14 = 41.83265 cm^2
3) find the height of the cylinder:
height = 7.3 x 3 = 21.9 cm
4) find the volume
V = base area x height = 41.83265 x 21.9 = 916.135035 cm^3
5) round to nearest tenth:
916. 1 cm^3
Answer:

Answer:
x/2+9=-15
Step-by-step explanation:
<h2>
Hello!</h2>
The answer is: D) 6.2 seconds
<h2>
Why?</h2>
When the egg hit the ground, the height will be equal to 0, so, from the given equation we need to find the roots or zeroes.
It's a quadratic function, we can find the roots using the quadratic equation:

So, from the given function we know that:

So, substituting we have:



So, since the time can not be a negative value, the correct option is:
6.18≈6.2 seconds
Hence, it takes 6.2 seconds to the egg to hit the ground.
Have a nice day!
