Answer:
KM = 4 units
Step-by-step explanation:
mathematically;
since l is on line segment KM
KM = KL + LM
substituting values;
5x + 4 = 5x + 1 + 3x + 3
5x + 4 = 8x + 4
8x-5x = 4-4
3x = 0
x = 0
KM = 5x + 4 = 5(0) + 4 = 4 units
To find the area shaded region we can see that the circle is equal to the side of the square
Hence
Diameter of circle=16cm
Radius=8cm
To find the area of the shaded region we have find the area of the square and subtract the area of the circle from it
Area of square=(side)2
=16x16
256cm2
Area of circle= πr2
=22/7x8x8
=201.14cm2
Area of shaded region=area of square-area of circle
=256-201.14
=54.9cm2
So it’s option D
HOPE IT WAS HELPFUL :)
Dannng I thought I seen this one before
3 because (l*w*h =v) and 3^3 is 27
tiles are needed .
<u>Step-by-step explanation:</u>
Here we have , Raj builds a side table in the shape of a cube. Each edge of the cube measures 15 inches. Raj wants to cover the top and four sides of the table with ceramic tiles. Each tile has an edge length of 5 inches. We need to find How many tiles will he need . Let's find out:
Total area to be covered by tile for covering the top and four sides of the table is
⇒ ![a^2+a^2+a^2+a^2+a^2](https://tex.z-dn.net/?f=a%5E2%2Ba%5E2%2Ba%5E2%2Ba%5E2%2Ba%5E2)
⇒
, Where a is edge of the cube measures 15 inches So , Area :
⇒ ![5(15)^2](https://tex.z-dn.net/?f=5%2815%29%5E2)
⇒ ![5(225)](https://tex.z-dn.net/?f=5%28225%29)
⇒ ![1125 in^2](https://tex.z-dn.net/?f=1125%20in%5E2)
Now , Area of each tile is :
⇒
, Where side is edge length of 5 inches
⇒ ![(5)^2](https://tex.z-dn.net/?f=%285%29%5E2)
⇒ ![25in^2](https://tex.z-dn.net/?f=25in%5E2)
So , Number of tile needed is
⇒ ![\frac{1125}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B1125%7D%7B25%7D)
⇒ ![45](https://tex.z-dn.net/?f=45)
Therefore ,
tiles are needed .
