➷ Use this formula:
Area of circle =
However, as we are using 3.14 for 'pi', we can write it like this:
Area =
'r' is the radius which is 12ft
Substitute this value into the equation:
Area =
Solve:
Area = 452.16
Multiply this value by 0.75 to get the answer:
452.16 x 0.75 = 339.12
339.12 square feet is being watered

Answer:
12 and 3.0984
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
So
So the correct answer is:
12 and 3.0984
<span>The length of each side of pentagonal church window with the perimeter of 60 inches is C. 12 inches. The perimeter (P) of a pentagon is the sum of its side lengths (s). Since pentagon has 5 sides, the perimeter of the pentagon is: P = 5s. If we know that the perimeter is 60 inches, the side length will be: 60 in = 5s. s = 60 in / 5. s = 12 in. The length of the side of the window is 12 inches.</span><span />
To get better at 12's:
Write down on your paper your 1's facts in column skip 5 and 11 going to 14 (a vertical line - line that goes up and down). To the right of that column, write your two's facts 0 to 8 and repeat again. Then you will have your 12's! Should look as follows
12's:
0 0 = 12 x0
1 2 = 12 x1
2 4 = 12 x2
3 6 = 12 x3
4 8 = 12 x4
6 0 = 12 x5
7 2 = 12 x6
8 4 = 12 x7
9 6 = 12 x8
10 8 = 12 x9
12 0 = 12 x10
13 2 = 12 x 11
14 4 = 12 x 12
