<u>Let's first gather all the information we have</u>:
<u>Let's put that into standard form</u>
- (h, k): center's coordinate
- r: radius
<u>To put that equation into general form</u>:
⇒ expand all the quadratics on one side and move the radius squared
to the same side as the quadratics
<u>Answer: x² + y² + 6x - 4y - 12 = 0</u>
<u></u>

Answer:
let required no be x
by doing crisscrossed multiplication
42=7x
dividing both side by 7
6=x
therefore x=6
therefore value of remaining no.is 6

Step-by-step explanation:
The volume (V) of a cone is calculated as
V = πr²h ( r is the base radius and h the perpendicular height )
To calculate the height h use the right triangle formed by the radius and the inclined side.
Given diameter = 22, then r = 22 ÷ 2 = 11 cm
Using Pythagoras' identity on the right triangle, then
h² + 11² = 61² , that is
h² + 121 = 3721 ( subtract 121 from both sides )
h² = 3600 ( take the square root of both sides )
h = = 60
Thus
V = π × 11² × 60
= 3.14 × 121 × 60 ≈ 22796.4 cm³ → a
