What is the radius of a cylindrical soda can with volume 512?

1 answer:

7 0

Volume of Cylinder = 2 * pi * radius (area of circle) * height of cylinder

radius * height = 512/(2 * pi)

Radius can not be solved for unless height is given

What is the perimeter of the triangle? Round to the nearest tenth.

Cerrena [4.2K]

Answer: 19.8 Units

Step-by-step explanation:

The triangle is shown in the attached figure, and have three vertices: $AB$ , $AC$ and $BC$ .

Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.

In this sense, the modulus $m$ is calculated as shown:

$m=\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}$

Hence, for each vector:

$AB=\sqrt{(-2-3)^{2} + (3-0)^{2}}=\sqrt{34}$

$AC=\sqrt{(-2-(4))^{2} + (3-(-3))^{2}}=\sqrt{40}$

$BC=\sqrt{(-4-3)^{2} + (-3-0)^{2}}=\sqrt{58}$

Now, the perimeter of a triangle is the sum of its three sides:

$AB+AC+BC=\sqrt{34} + \sqrt{40} + \sqrt{58}$

Finally:

$AB+AC+BC=19.77 \approx 19.8$

What is 17/147 in lowest terms

katovenus [111]

Hi there!

To find your answer, let us see what number can go evenly into 17 and 147.

$\frac{17}{147}$

Since it looks like nothing can go into each number evenly, $\frac{17}{147}$ is already simplified down to its lowest terms and it can't go any lower than that.

Hope this helps! :D

The base length of a triangle is 12 feet and the height is 6 feet. What is the area of the triangle?

kramer

The formula to find the area of a triangle is:

$\sf~A=\dfrac{1}{2}bh$

Plug in what we know:

$\sf~A=\dfrac{1}{2}(12)(6)$

Multiply:

$\sf~A=\boxed{\sf36}$
