Help needed ASAP!!! no links pls. a dartboard is made up of concentric circles with the following radii:
circle a: r= 2in
circle b: r= 4in
circle c: r= 6in
circle d: r= 10in
what is the probability that the dart will NOT hit inside the c circle.

step-by-step explanation:

6mm^3 or .6cm^3

      216

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
