Answer:
349800
4
Step-by-step explanation:
First Part:
The question tells you to multiply by 10 to the power of 4.
This implies that you can move the decimal point 4 numbers to the right
When you move the decimal two numbers to the right you get 3498
Then you got to move it two more numbers to the right
3498 can also be written as 3498.0000000000 (infinite amount of zeros)
So moving the decimal two more places you get 349800
Second Part:
10^4 = 10 * 10 * 10 * 10
= 10000
Count the zeros you get 4.

The key to this problem is ignoring all the information that you don't need. You really don't care about the coordinates for T, U, or V. Just W is all that matters. So make a graph, label the X and Y axis, and put a point at (1,5). Now simply turn the entire paper clockwise 90 degrees. If you do this, you'll see that what was the X axis is now the Y axis. And what was the Y axis is now the X axis. Label the axis again, and read the location of the point you marked. If you do so, you'll see that you have to go 5 spaces along the X axis, hence the 5. And you'll go 1 space down on the Y axis, hence the -1.
So the coordinates of W(1,5) rotated 90 degrees clockwise around (0,0) changes to (5,-1).</span>
Answer:
Step-by-step explanation:
The radius of the circle is 7 cm.
The two legs of the triangles are 7cm as well.
Area of a trinagle is ( base × height )/2.
Multiply the value by 2 since there are two triangles.
Calculate the area of the circle.
The radius is given.
Take 
as 
Subtract the area of the two triangles from the area of the whole circle.
The area of the shaded part is 105 cm². The total area of the shape is 154cm².
