ANSWER

Volume of Cone = 37.7cm^3

EXPLANATION

$\begin{gathered} V\text{ = }\Pi\ast r^2\frac{h}{3}^{} \\ \text{ = 3.142}\ast3^2\ast\frac{4}{3}=37.699cm^3 \end{gathered}$

Hence, the Volume of Cone = 37.7cm^3

The leaning tower of Pisa currently "leans" at a 4 degree angle and has a vertical height of 55.86 meters. How tall was the lean

Marizza181 [45]

Answer:

56 meters.

Step-by-step explanation:

Please find the attachment.

Let the leaning tower's be h meters tall, when it was originally built.

We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.

Since we know that cosine relates the adjacent and hypotenuse of a right triangle.

$\text{Cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}$

Upon substituting our given values we will get,

$\text{Cos (4)}=\frac{55.86}{h}$

$h=\frac{55.86}{\text{Cos (4)}}$

$h=\frac{55.86}{0.99756405026}$

$h=55.996\approx 56$

Therefore, the leaning tower was approximately 56 meters, when it was originally built.

Elenna [48]

Your domain would include only positive integers, or zero. The value of the buns cannot be negative; in other words, you cannot have a negative number of buns. The same principle applies to boxes. However, you can have zero buns or zero boxes. Hope this helps.

a dime is dropped from a building at 1.024 ft . if the equation for height as a function of time is h(t)=-16t^2+ initial height

babunello [35]

Answer:

The dime hits the ground after 8 sec.

Step-by-step explanation:

Set h(t) = -16t^2 + h(0) equal to 0: -16t^2 + 1,024 ft = 0, or:

16t^2 = 1,024 ft, or:

t^2 = 64 ft^2

Then t = +8 sec

The dime hits the ground after 8 sec.
