You have 4 walls, 2 with length 12 feet, 2 with length 15 feet and each of them has a height of 12 feet
so you sum all the lengths and then multiply it by the height to get the total area
total length=2*(12+15)
=2*(27)
=54
total area=total length*ceiling height
=54*12
=648 feet^2 to cover all walls with wallpaper
Given:
The point is located at P(4,7).
It is translated along 
.
To find:
The image of the given point after the translation.
Solution:
The point is translated along . So, the rule of translation is defined by:
The point is located at P(4,7).
Using the above rule, we get
The image of given point after the translation is (5,10).
Therefore, the correct option is A.
Answer:
Hence the required equation of circle is
(x - 4)² + ( y - 1)² = 4
Step-by-step explanation:
The equation of a circle whose center (h, k) and radius r is given-
(x - h)² + (y - k)² = r²
Here given that-
Center = ( 4, 1) & r = 2
Equation of circle-
<em>( x - 4)² + ( y - 1)² = 2²</em>
<em>(x - 4)² + ( y - 1)² = 4</em>
<em>x² + 16 - 8 x + y² + 1 - 2 y = 4</em>
<em>x² + y² -8 x - 2 y + 13 = 0 </em>
Hence the required equation of circle is
(x - 4)² + ( y - 1)² = 4
0R
x² + y² - 8 x - 2 y + 13 = 0
