Given: O is the midpoint of line MN<br> OM=OW<br> Prove: OW=ON
grigory [225]
Given:
O is the midpoint of line MN
OM = OW

To prove:  OW = ON

<u>Statement</u>                                 <u>Reason</u>
1> OM = OW  -------------------------> Given
2> OM = ON ---------------------------> O is the midpoint of line MN
                                                           i.e Point O bisects line MN
3> OM = OW --------------------------> From statement <1>
4> ON = OW  -------------------------> OM = ON (Statement <2>)
     OW = ON
              
                                                                    <u>proved!!</u>

A right triangle has sides of lengths 18 ​, 24 ​, and 30 units. What is the area of the​ triangle? Draw the shape on a grid to h
Elden [556K]

Answer:216

Step-by-step explanation:The formula to find the area of a triangle is Length times Base divided by 2. The length of the triangle could be 18 or 24, but that doesn’t matter. The base could also be 18 or 24, but that also doesn’t matter, because the hypotenuse (the longest part of a right triangle, in this case being 30), is not a part of the formula. 18 times 24 is 432, and 432 divided by 2 is 216. So the area is 216

german

Answer:

Volume of Cone =

=  \frac{1}{3}\pi (2)^2 (4)\\\\=\frac{1}{3}(3.14)(4)(4)\\\\=\frac{1}{3}\times 3.14\times 16 \\\\=\frac{1}{3}\times50.24\\\\=16.746\\\\\approx16.75 \texttt {ft} ^3

Thus, Volume = 16.75 cubic feet

Step-by-step explanation:

Volume of a cone is given by the formula  

V=\frac{1}{3}\pi r^2 h

Where r is the radius and

h is the height

Given radius r = 2 and

height is 2 times that.

So height is 2*2 = 4

Plugging these into the formula we get:

Volume of Cone =

=  \frac{1}{3}\pi (2)^2 (4)\\\\=\frac{1}{3}(3.14)(4)(4)\\\\=\frac{1}{3}\times 3.14\times 16 \\\\=\frac{1}{3}\times50.24\\\\=16.746\\\\\approx16.75 \texttt {ft} ^3

Thus, Volume = 16.75 cubic feet
