If Raj randomly chooses a point in the square below, what is the probability that point is not in the circle? Assume that pi = 3

hodyreva [135]

Answer:

49.7%

Step-by-step explanation:

A cdircle is located within a square.

Area of the circle

Area = $\pi$ $r^{2}$ , where r = 4 units.

Area Circle = 50.3 units^2

Area of the square

Area = l*w or l^2 for a square, since l = w

Area = (10 units)^2

Area = 100 units^2

Area in the square but outside the circle

This is the difference [Square minus Circle Areas]

Square minus Circle Areas = 100 - 50.3 or 49.7 units^2

Probability

The probability of picking a point in the square that is not in the circle is the ration of the two areas: [Outside Circle/Square]x100%

(49.7 units^2)/(100 units^2)x100% = 49.7%

Carlos plots a circular planter's wall on a computer. He determines that the circle that defines the part of the planter wall th

lyudmila [28]

1. You have that the circle that defines the part of the planter wall which gets watered by the sprinkler is: (x−10)²+(y+12)²=36.

2. The standard form for the equation of a circle is:

(x-h)²+(y-k)²=r²

(h,k) is the center point.
r is the radius.

3. Keeping this on mind, you can find the value of the radius, as below:

r²=36
r=√36
r=6 m

4. Then, the diameter of the circle is:

D=2r
D=2(6m)
D=12 m

What is the diameter, in meters, of the circular area that gets watered by the sprinkler?

The answer is: 12 m
