A circle has a diameter
torisob [31]

The circumference of circle is 20.096 units

<em><u>Solution:</u></em>

Given that circle has a diameter  with endpoints at (10, 8)  and (5, 4)

To get the diameter, find the distance between the end points

<em><u>The distance between two points is given by formula;</u></em>

d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}

Here the points are (10, 8)  and (5, 4)

(x_1, y_1) = (10, 8)\\\\(x_2, y_2) = (5, 4)

Substituting the values we get,

\begin{aligned}&d=\sqrt{(5-10)^{2}+(4-8)^{2}}\\\\&d=\sqrt{(-5)^{2}+(-4)^{2}}=\sqrt{25+16}=\sqrt{41}\end{aligned}

d = \sqrt{41} = 6.4

Thus the diameter is 6.4 units

<em><u>The  circumference of the circle is given by formula:</u></em>

c = \pi d

Where "d" is the diameter of circle

c = 3.14 \times 6.4 = 20.096

Thus circumference of circle is 20.096 units

Which of the following statements best summarizes the results of scientific studies on the nutritional value of organically grow
iragen [17]
The correct answer should be  D. Studies have been inconclusive regarding the nutritional value of organically grown food and conventionally grown food.

There has yet to be found a conclusive evidence that organic food is better. Most of the things that people hate about regular food is easily removed either by washing the food such as fruits or vegetables or by cooking them in any way. Risks of illnesses and diseases is also not related to the difference between them.
