Answer:

The equation of the circle is (x+3)^2 + (y-4)^2 = 16.

Step-by-step explanation:

The equation of a circle can be calculated if the center and the radius are known. The equation of a circle is given by (x-h)² + (y-k)² = r²

Where (h, k) = center coordinates and r = radius.

Answer:

$A_s=179 \ yd$

Step-by-step explanation:

Area of Circle can be calculated using following formula

$A=\pi r^{2}$

Where r is radius of circle

Area of outer circle (r=11 yd)

$A_1=\pi (11)^{2}\\A_1=379.94 \ yd$

Area of inner circle (r=8 yd)

$A_2=\pi (8)^{2}\\A_2=200.96 \ yd$

Area of shaded region

$A_s=A_1-A_2$

$A_s=379.94-200.96\\A_s=179 \ yd$

PLEASE GIVE A GOOD EXPLANATION FOR A FREE BRAINLIEST: 26.8 + 0.65 - 0.028 =

zmey [24]

$\boxed{27.422}$

We will use order of operations to add and subtract from left to right to solve this equation.

26.8 + 0.65 = 27.45

The equation now looks like:

27.45 - 0.028 = 27.422

Therefore, your answer is 27.422.
