What are the center and radius f the circle with equation xthe power of 2 +y power of 2 -4x -6y +8=0

Dovator [93]

x² +y² -4x -6y +8=0
(x² -4x) +(y² -6y) = -8
We are going to complete square for x and y,
it should look like a²+2ab+b² = (a +b)², or a²-2ab+b² = (a -b)²,

(x²-2*2x+2²) -2² + (y²-2*3y +3²)-3²=- 8
(x-2)²+(y-3)²-4-9=-8
(x-2)²+(y-3)²=-8+13
(x-2)²+(y-3)²=5

Formula a circle (x-h)²+(y-k)²=R², where vertex has coordinates (h, k)

So , for our circle vertex (2,3) and radius = √5

A cylinder has a volume of 540 cm cubed. if the height of the cylidner is 15 cm, find the radius.

Tamiku [17]

You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.
$V=540=\pi r^2*h= \pi r^2*15$
Then,
$r^2= \frac{540}{15 \pi }$
So, $r= \sqrt{\frac{540}{15 \pi }}$
radius is approximately 3.4cm

Hope this helps.
