(x+2)² +(y+10)² =4
(x-h)² +(y-k)² =r²
(x-(-2))² +(y-(-10))² =2²
h=-2,
k=-10
Center is (-2, -10).
Radius r=2.
Answer C. Center is (-2, -10), r=2.
Answer:
n>-7/3
Step-by-step explanation:
12n+35>7
35-35=0
7-35=-28
12n>-28
12/12=1
-28/12≈-2.3=-7/3
n>-7/3
Answer: approximately 3.5 meters.
Step-by-step explanation:
Given: Circumference of the smaller circle is approximately 11 meters.
Circumference of a circle =
, where d= diameter.
Ratio of circumference to diameter = 
As per given,
![\pi=\dfrac{11}{d}\\\\\Rightarrow\ d=\dfrac{11}{\pi}\\\\\Rightarrow\ d=\dfrac{11\times7}{22}\ \ \ [\pi=\dfrac{22}7]\\\\\Rightarrow\ d=\dfrac72=3.5\ meters](https://tex.z-dn.net/?f=%5Cpi%3D%5Cdfrac%7B11%7D%7Bd%7D%5C%5C%5C%5C%5CRightarrow%5C%20d%3D%5Cdfrac%7B11%7D%7B%5Cpi%7D%5C%5C%5C%5C%5CRightarrow%5C%20d%3D%5Cdfrac%7B11%5Ctimes7%7D%7B22%7D%5C%20%5C%20%5C%20%5B%5Cpi%3D%5Cdfrac%7B22%7D7%5D%5C%5C%5C%5C%5CRightarrow%5C%20d%3D%5Cdfrac72%3D3.5%5C%20meters)
Hence, the diameter of the smaller circle is approximately 3.5 meters.
