It should be D Vietnam I believe and by the way you have this under mathematics.
Answer: See below
Step-by-step explanation:
<u>Area of the square</u> = l*w = 11*11 = 121
<u>Area of the circle</u> = pi r^2 = pi*1^2 = 3.142
<u>Part A</u>
P(hitting the circle) = 3.142 / 121 = 0.026 which is closer to 0.
<u>Part B</u>
P(hitting the outside portion) = 1 - 0.026 = 0.974 which is closer to 1.
(2x + 5) / (3x + 5) as ur answer
Answer:
radian
Step-by-step explanation:
We know that angle for a full circle is 2
In the given figure shape is semicircle
hence,
angle for semicircle will be half of angle of full circle
thus, angle for given figure = half of angle for a full circle = 1/2 * 2
= 
Thus, answer is
radian
alternatively, we also know that angle for a straight line is 180 degrees
and 180 degrees is same as
radian.
