Which equation represents the circle described? The radius is 2 units. The center is the same as the center of a circle whose eq

Serhud [2]

Answer:

$(x-4)^2+(y-3)^2=2^2$

Step-by-step explanation:

The given circle has equation; $x^2+y^2-8x-6y+24=0$

Comparing to the general equation of the circle: $x^2+y^2+2ax+2by+c=0$

We have $2a=-8\implies a=-4$ and $2b=-6\implies b=-3$

The center of this circle is (-a,-b)=(4,3).

The required circle has radius r=2 units.

The equation of a circle, given the center (h,k) and radius r, is given by:

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

We substitute the values to obtain $(x-4)^2+(y-3)^2=2^2$

Find the area of a circle with a circumference of 5.5 pi=3.14

Olegator [25]

Answer:

2.43 (units)

Step-by-step explanation:

Circumference of a circle is defined by C=2pi*r

Solving that equation for r --> 5.5 = 2* 3.14 * r

r=0.88 unit

Area of a circle = A= pi * r^2

Solve this equation by plugging in the r we just found. A = 3.14 * (0.88^2)

Answer: 2.43 units
