What’s the distance between (3,4) , (7,2)

Reptile [31]

Answer:

$D= 4.47$

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (3,4)$

$(x_2,y_2) = (7,2)$

Replacing these values in the distance formula

$D =\sqrt{(7-3))^2+(2-4)^2}$

$D =\sqrt{(4)^2+(-2)^2}$

$D =\sqrt{16+4}$

$D =\sqrt{20}$

$D= 4.47$

A cylindrical soup can has a height of 8 in. and a radius of 3in. If the height is doubled on a second soup can, what will be th

kykrilka [37]

Answer:

The ratio of the volumes of the two soup cans is 2.

Step-by-step explanation:

The volume of a cylinder can be written as:

$V=\pi r^2h$

where r is the radius of the base and h is the height.

If the height of the second cylinder doubles the height of th first cylinder, the ratio of volume between the second and the first cylinder is:

$\dfrac{V_2}{V_1}=\dfrac{\pi r^2 h_2}{\pi r^2 h_1}=\dfrac{\pi r^2 (2h)}{\pi r^2 h}=\dfrac{2}{1}=2$

The ratio of the volumes of the two soup cans is 2.

Can someone please help me find the volume?

Mrac [35]

Answer:

Step-by-step explanation:

Volume = base * height.

The area of the base = base * height/2

That means the area of the triangular base is 8 * 5.1/2 = 20.4

The height is 9, so the volume is 20.4 * 9.

That means the volume is 183.6, which is C
