What is the best approximation for the area of a circle with a diameter of 13 meters?

1 answer:

4 0

First, find the radius of the circle. The radius of a circle is half the diameter. r=13/2=6.5

Second, use the equation A=pi * r^2 to find the area of the circle.
A=(3.14) * (6.5^2) = 132.665m^2

so the answer is 132.7 m^2.

Anton will be constructing a segment bisector with a compass and straightedge, while Maxim will be constructing an angle bisecto

elena-14-01-66 [18.8K]

A bisector is a line that divides either a line or an angle into two proportionate parts or angles. Thus, Anton's bisector would divide the segment into two equal parts, while Maxim's bisector would divide the angle into two equal angles.

The similarities between their construction are:

Intersecting arcs through which the bisector would pass are required.
The arcs are dawn using the same radius of any measure.
The edges of the arc of the given angle, and the ends of the segment are used as centers.

The differences between their construction are:

Anton has to draw two intersecting arcs above and below the segment. While Maxim would draw two intersecting arcs within the lines forming the angles.
Anton's bisector would be perpendicular to the segment, while Maxim's bisector would be at an angle which is half of the initial angle.

What I did was I subtracted 4500 minus 500 because it was a fee then I divide 4400 by 35 and I got 125 people.
