You can work out the radius firstly.
The length of one side of a decagon depends on the specific dimensions of the decagon, as it can vary based on whether it is regular (all sides and angles are equal) or irregular. For a regular decagon, if the radius of the circumscribed circle (circumcircle) is known, the length of each side can be calculated using the formula: ( s = r \times \sin(\pi/10) \times 2 ), where ( r ) is the radius. If the perimeter or area is known, the side length can be derived accordingly.

To draw a regular decagon using a compass, start by drawing a circle with your compass. Next, mark a point on the circle to serve as one vertex of the decagon. Then, use the compass to construct the radius and divide the circle into ten equal segments by marking points at equal angles (36 degrees apart). Finally, connect these points with straight lines to form the decagon.
Given the regular decagon what is the measure of each numbered angle? There is a one in the first triangle, a three in the second, and a two in the sixth triangle in the decagon. Here are the answer choices m1=72, m2=18, m3=36 m1=18, m2=36, m3=72 m1=36
10.4 cm
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
Its radius is 4.8 cm, rounded to the nearest tenth.
The area of a circle to the nearest tenth if its radius is 4.5 is: 63.6 square units.
The area of a regular pentagon with a radius of 7 is 10.1716. If the radius was 5, the area would be 7.26543.
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
Here are some math words: integers, decagon, volume, radius, area, diameter, and algebra.
Chords come in various lengths, which may be longer, shorter, or the same length as the radius.
