Answer:
9 square kilometers
Step-by-step explanation:
Let's round the width to 2.0 kilometers, and round the length to 4.5 kilometers.
We know that area is length times width, so
A = lw
A = 2.0*4.5
<u>A = 9.0 square kilometers</u>
If we do this on the calculator, it's around 9.36 square kilometers, so our estimate was good.
Answers:
The length of XY is 4
The length of ZW is 6
Because we don't get the same length (for XY and ZW), this means that the segments are not congruent.
-------------------------------------------------------------
To find the length of segment XY, you can count the number of spaces between -7 and -3 to get 4 units. Or you can subtract and use the absolute value notation to ensure the result is positive
|-7-(-3)| = |-7+3| = |-4| = 4
Do the same for segment ZW.
|2-8| = |-6| = 6
Answer:
true
Step-by-step explanation:
X=-6
First thing to do is get the x one side then get rid of the number next to it to get x by itself lastly divide
Radius of ball is 6 inches. Then the volume is 904.32 
<u>Solution:</u>
Given that, radius of a ball is 6 inches.
We have to find the volume of the ball with 6 inches radius.
Now, we know that, a ball will be in a shape of sphere, so we have to use the volume of a sphere formula to find the volume of the ball.
<em><u>The volume of sphere is given as:</u></em>
where r is the radius.
Here in our problem, r = 6
Hence the volume is 904.32
