Answer:
<h2>A = 36π yd² ≈ 113.04 yd²</h2><h2>C = 12π yd ≈ 37.68 yd</h2>
Step-by-step explanation:
The formula of an area of a circle:

The formula of a circumference of a circle:

<em>r</em><em> - radius</em>
<em />
We have <em>r = 6yd</em>.
Substitute:


If you want round the answers, then use <em>π ≈ 3.14</em>


Answer:
Ok, as i understand it:
for a point P = (x, y)
The values of x and y can be randomly chosen from the set {1, 2, ..., 10}
We want to find the probability that the point P lies on the second quadrant:
First, what type of points are located in the second quadrant?
We should have a value negative for x, and positive for y.
But in our set; {1, 2, ..., 10}, we have only positive values.
So x can not be negative, this means that the point can never be on the second quadrant.
So the probability is 0.
Add 5 on both sides
Make the denominators the same

Multiply 13 on both sides


A= 58°B= 83° because you add the straight angle which is 90 plus the other number and subtract it by 180 because a triangle has 180°
