C = 36 pi units = 2 pi r. Thus, r = 36 pi / (2 pi) = 18 units.
Thus, A = pi*r^2 = pi*(18 units)^2
Answer:
1. 1
1. 13π.
--
20
explain:
1. 1 because any any non-zero expression raised to the power of 0 equals 1
13π.
2. --. because to convert into radian measure multiply by. π
20. ----
180°
Answer:
The correct answer is B. Mark the points of intersection between the three circles.
Answer:
(a) Each piece is “berry or cherry” with probability p = 1/2. The proba-
bility of only berry or cherry pieces is p
12 = 1/4096.
Step-by-step explanation:
(b) Each piece is “not cherry” with probability 3/4. The probability all 12
pieces are “not pink” is (3/4)12 = 0.0317.
(c) For i = 1, 2, . . . , 6, let Ci denote the event that all 12 pieces are flavor i.
Since each piece is flavor i with probability 1/4, P[Ci
] = (1/4)12. Since
Ci and Cj are mutually exclusive,
P[F1] = P[C1 ∪ C2 ∪ · · · ∪ C4] = X
4
i=1
P[Ci
] = 4 P[C1] = (1/4)11
