What is the distributive property of32 +44 =

The ratio of the lateral surface area of cone A to the lateral surface area of cylinder B is equal to $r = \frac{1}{2}\cdot \frac{\sqrt{r^{2}+h^{2}}}{h}$ . (Correct choice: False)

<h3>What is the ratio of lateral area of cone to the lateral area of the cylinder?</h3>

In accordance with space geometry, the lateral areas of the cone and cylinder are described by the following equations:

Cone

$A_{l} = \pi \cdot r \cdot \sqrt{r^{2}+h^{2}}$ (1)

Cylinder

$A_{l} = 2\pi\cdot r\cdot h$ (2)

If we divide (2) by (1), then we have the following ratio:

$r = \frac{1}{2}\cdot \frac{\sqrt{r^{2}+h^{2}}}{h}$

The ratio of the lateral surface area of cone A to the lateral surface area of cylinder B is equal to $r = \frac{1}{2}\cdot \frac{\sqrt{r^{2}+h^{2}}}{h}$ . (Correct choice: False)

I NEED HELP ASAP! Will give brainliest!!! RANDOM ANSWERS WILL BE MODERATED

Salsk061 [2.6K]

You need to prove that <A = <E
since c is the midpoint of line AE then AC = EC
i dont remember the name of the theroem that states that when a triangle has two sides and an angle in common that it is congruent i think it called SAS congruence therom. use that to prove that the <| s are congruent then use CPCTC to prove that <A = <E. then prove that they are || by usint the int angle therom.

Convert €3.2 per kilogram to unit price dollars per pound

MatroZZZ [7]

We get 1.45 dollars per pound when we convert 3.2 Euros per kilogram to dollar per pound.

According to the question,

We have the following information:

3.2 Euros per kilogram

We need to convert its units into dollars per pounds.

We know that 1 Euro is approximately equal to 1 US dollar and 1 kilogram of weight is equal to 2.205 pounds.

(Note that there are various conversions from Euro to dollars which have 1 Euro equal to 1.00755 and many other values. In this case, we have rounded it off to 1 to avoid any confusion.)

(We know that per means the unit given is in divide.)

So, we have:

(3.2*1)/(1*2.205)

3.2/2.205

1.45 dollar per pounds

Hence, the conversion to dollars per pounds is 1.45 dollar per ponds from Euros per kilogram.
