First, find the area of the larger sector (the 360-130=230 degree sector), then add the area of the triangle.
area of the larger sector:(230/360)π*11.1²≈247.17
area of the triangle when two sides and the angle between the two sides are given: (absinФ)/2. In this case, a=11.1, b=11.1, Ф=130
(11.1*11.1*sin130)/2≈47.19
the total area is 247.17+47.19≈294.4
Please use your calculator to double check my numbers.
Answer:
3/32
Step-by-step explanation:
Labels from 1 to 8:
The probability that he gets a number less than 4 (1, 2, 3) is 3/8
The probability to get a multiple of 4 (4, 8) is 2/8 = 1/4
So
The probability that he gets a number less than 4 or a multiple of 4:
= 3/8 x 1/4
= 3/32
Answer
3/32
