Center ( 9,-8 ), passes through ( 19,22 )
katovenus [111]
Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²

so given
center at (9,-8)

(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²

input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r

well, the equation is
(x-9)²+(y+8)²=1000

The 8 foot diameter circular table has a 4 foot wide extension. What is the total area with the extension? How does the area com
Ann [662]
To compare the areas of the table without the extension and the table with the extension, you would need to find the areas of both. See the attached page for the area of the table with the extension. To compare this to a table with a diameter of 10 ft, you need to calculate the area of the table that has a diameter of 10 feet. See the attached page for this information as well. When you're done make a comparison statement giving both pieces of information in your answer.
