We have been given that the diameter of a smaller circle is 7 km and the width of the circular path is 0.5 km. We are asked to find the area of the path.
The area of the path will be equal to area of larger circle minus area of smaller circle.
, where r represents radius of circle.
We know that radius is half the diameter, so radius of smaller circle would be 
km.
The radius of the larger circle will be radius of smaller circle plus width of the path that is 
km.
Therefore, the area of the circular path is approximately 11.8 square km.
Answer:
Dilation transformation
Step-by-step explanation:
Dilation transformation maps the large triangle onto the small triangle.
Answer:
710,000
Step-by-step explanation:
Make the number whose last four are <em>0</em><em>0</em><em>0</em><em>1</em> through <em>4</em><em>9</em><em>9</em><em>9</em> in the <em>next</em><em> </em><em>lower </em><em>number</em><em> </em>that <em>ends</em> in <em>0</em><em>0</em><em>0</em><em>0</em><em>.</em>
<em>for</em><em> </em><em>example</em><em>:</em>
265,427 rounded to the nearest ten thousand is 270,000
81 because 81 is a perfect square and 27 times 3 =81
