Probability =
(number or amount of possible successes)(total number or amount of possible outcomes)
Area of any circle is (pi) x (radius squared)
Area of the whole board = (pi) x (13 squared) = 169 pi square inches
Area of the shaded region = (pi) x (5 squared) = 25 pi square inches
Probability = (success area) / (total possible area) = 25pi/169pi = <u>0.15 </u>(rounded)
Notice that if you do it my way ... keep 'pi' in the fraction ... you don't even
need to know what the value of 'pi' is, because there's one in the top and
bottom of the fraction, and they cancel.

Answer:
Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.
Answer:
18a^2
Step-by-step explanation:
Multiply the numbers together. Multiply the variables together.
(-3a)(-6a) = (-3) * (-6) * a * a = 18a^2
-3 times -6 = 18 since negative times negative is positive, and 3 * 6 = 18.
Also a * a = a^2.
Answer: 18a^2
