Answer:
x = 5
Step-by-step explanation:
Length of diameter is 2.86 cm
<em><u>Solution:</u></em>
Given that circumference of a circle is 8.97 cm
To find: length of diameter
We can use the formula for circumference of circle to find radius and then we can find diameter
<em><u>The circumference of circle is given as:</u></em>
Where "r" is the radius of circle and is a constant equals to 3.14
Substituting c = 8.97 and
Thus radius of circle is 1.4283 cm
<em><u>Finding diameter of circle</u></em>
diameter = 2(radius)
diameter = 2(1.4283) = 2.8566
On rounding to two decimal point we get, 2.86
Thus length of diameter is 2.86 cm
B is not a solution to the graph
(100 - 7) + 100 = 193
(110 + 10) + 100 = 220
193 : 220
I haven't found a way to simplify
You are giving five radii (1, 1.5, 2, 2.5 and 3 feet) but only two colors, so I do not know which radii are for colors blue and yellow.
I will explain the procedure in detail, and so you can apply it knowing the radii of each color.
The probability of heating any circle equales the ratio of its are and the area of the square board.
The area of the square board is 10feet * 10 feet = 100 ft^2.
The area of any circle is π*(r^2).
So you can make this table
Color radius area ratio of area of the circle
to area of the square board
blue 1.0 π(1^2) = 3.14 3.14 / 100 = 0.0314
yellow 1.5 π(1.5^2) = 7.07 7.07/ 100 = 0.0707
x 2.0 π(2^2) = 12.57 12.57/100 = 0.1257
y 2.5 π(2.5^2) = 19.63 19.53 / 100 = 0.1953
z 3.0 π(3^2) = 28.27 28.27 / 100 = 0.2827
Then you have to sum the ratios for the colors blue and yellow.
In the case shown in the table that is 0.0314 + 0.0707 = 0.1021
I realize that if I sum the ratios for the second and third circles in the table, the result is 0.0707 + 0.1257 = 0.1964, which is the option A of the list.
So if the blue and yellow circles are those with radii 1.5 and 2 the answer is the option A.
With that explanation you are able to find the probability requested.
