Determine the equation of the circle graphed below. ( please help me )

Brums [2.3K]

Answer:

$Equation : \\(x+3)^2 + ( y -2)^2 = 36$

Step-by-step explanation:

For standard form the circle's equation we need the centre of the circle and the radius.

Step 1: Find the centre

If the centre is not given find the end points of the diameter

and then find the mid point.

Let the end points of the diameter be : ( - 3 , 8 ) and ( -3 , -4 )

The mid-point of the diameter is :

$Mid-point = (\frac{-3 + - 3}{2}, \frac{-4+8}{2}) = (-3, 2)$

Therefore, centre of the circle = ( -3 , 2 )

Step 2 : Find radius

$Radius = \frac{Diameter }{2}$

Diameter is the distance between the end points ( -3 , 8) and ( -3 , -4 )

That is ,

$Diameter = \sqrt{(-3-(-3))^2 + ( -4 -8)^2}\\$

$= \sqrt{(-3 + 3)^2 + (-12)^2}\\\\=\sqrt{0 + 144}\\\\=12$

Therefore ,

$Radius = \frac{12}{2} = 6$

Step 3 : Equation of the circle

Standard equation of the circle with centre ( h ,k )

and radius ,r is :

$(x - h)^2+(y -k)^2 = r^2$

Therefore, the equation of the circle with centre ( -3, 2)

and radius = 6 is :

$(x - (-3))^2 + (y - 2)^2 = 6^2\\\\(x + 3)^2 + (y - 2)^2 = 36$

The Pythagorean theorem is true for all similar triangles. A. True B. False

Afina-wow [57]

False. It only relates to the sides of a right triangle in a simple way, so that if the lengths of any two sides are known, the length of the third side can be found.

Jude says that the volume of a square pyramid with base edges of 9.7 in and a height of 9 in is equal to the volume of a cylinde

earnstyle [38]

Answer:

The correct option is;

Yes, his calculations are correct and the volumes for figures are equal

Step-by-step explanation:

The volume, V, of a square (of side s) pyramid of height h = $\frac{1}{3} \times s^2 \times h$

Where:

s = 9.7 inches

h = 9 inches

We have;

$V = \frac{1}{3} \times 9.7^2 \times 9 = \frac{1}{3} \times 94.09 \times 9 = \frac{1}{3} \times 846.81 = 282.27 \approx 282 \ in^3$

The volume, $V_c$ , of a cylinder of radius r = Base area × Height, h = (π×r²)×h

Where:

Base area = π×r²

r = Radius of the cylinder = 5.47 inches

h = Height of the cylinder = 3 inches

$V_c$ = π × 5.47² × 3 = π × 29.9209 × 3 = π × 89.7627 = 281.998 ≈ 282 m³

Therefore, Jude is correct.
