The width of a circular track is 2 meters. If the radius of the outer circle is 6 meters, find the area of the track.​
Vilka [71]

Answer:

62.8 \:  {m}^{2}

Step-by-step explanation:

Radius of outer circle = 6 m

Width of the track = 2 m

So, radius of inner circle = 6 - 2 = 4 m

Area of the track = Area of outer circle - Area of inner circle

= \pi {6}^{2}  - \pi {4}^{2}  \\  \\  = \pi( {6}^{2}  -  {4}^{2} ) \\  \\  = 3.14 \times (36 - 16) \\  \\  = 3.14 \times 20 \\  \\  = 62.8 \:  {m}^{2}

Prove that x-s-t is a factor of x^3 - s^3 -t^3 -3st(s+t)
inessss [21]
1. Introduction. This paper discusses a special form of positive dependence. Positive dependence may refer to two random variables that have a positive covariance, but other definitions of positive dependence have been proposed as well; see [24] for an overview. Random variables X = (X1, . . . , Xd) are said to be associated if cov{f(X), g(X)} ≥ 0 for any two non-decreasing functions f and g for which E|f(X)|, E|g(X)|, and E|f(X)g(X)| all exist [13]. This notion has important applications in probability theory and statistical physics; see, for example, [28, 29]. However, association may be difficult to verify in a specific context. The celebrated FKG theorem, formulated by Fortuin, Kasteleyn, and Ginibre in [14], introduces an alternative notion and establishes that X are associated if ∗ SF was supported in part by an NSERC Discovery Research Grant, KS by grant #FA9550-12-1-0392 from the U.S. Air Force Office of Scientific Research (AFOSR) and the Defense Advanced Research Projects Agency (DARPA), CU by the Austrian Science Fund (FWF) Y 903-N35, and PZ by the European Union Seventh Framework Programme PIOF-GA-2011-300975.
