Your vacation cabin on the lake has three rooms. The bathroom is 12' X 6', the bedroom is 14' X 18' and the great room is 20' X

GarryVolchara [31]

Answer: $9240\ ft^3$

Step-by-step explanation:

Given

Dimension of the bathroom is $12'\times 16'$

Dimension of the bedroom is $14'\times 18$

Dimension of the great room is $20'\times 30'$

Height of the ceiling is $h=10'$

Total area of the cabin

$\Rightarrow A=12\times6+14\times 18+20\times 30\\\Rightarrow A=72+252+600\\\Rightarrow A=924\ ft^2$

Volume of the cabin is $V=A\times h$

$\Rightarrow V=924\times 10\\\Rightarrow V=9240\ ft^3$

What is the radius of the circle given by the equation below? x2 - 2x + y2 - 2y - 98 = 0?

valina [46]

Complete the square for the given equation
x² - 2x + ____ + y² - 2y + _____ = 98
x² - 2x + (1) + y² - 2y + (1) = 98 + (1) + (1)
(x - 1)² + (x - 1)² = 100
(x - 1)² + (x - 1)² = 10²

Now the equation is in the form (x - h)² + (y - k)² = r²

Radius = 10
