How do you find the area of an inscribed circle in a octagon?
Find the area of a regular octagon inscribed in a circle with radius 1 unit. Break the octagon into 8 congruent triangles. You will find the area of one triangle and multiply that by 8 to find the area of the whole octagon.
Can an octagon be inscribed in a circle?
A regular octagon is inscribed in a circle of radius 15.8 cm. The octagon can be divided into 8 triangles congruent to ACB and hence the measure of the angle ACB is 360/8 = 45 degrees. Thus the triangle ACB is isosceles, with two sides of length 15.8 cm each and the angle between them measuring 45 degrees.
How do you find the area of an inscribed circle?
When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle. That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units. The area of a circle of radius r units is A=πr2 .
How do you find the perimeter of an octagon inscribed in a circle?
The octagonal perimeter P is 8s or 612.3 cm. The octagon inscribed inside a circle of 100 cm radius, will have 8 isosceles triangles. The apex angle of each isosceles triangle will be 45 degrees (= 360/8) and each of the base angles = (180–45)/2 = 67.5 deg. Each of the equal sides will be 100 cm.
How to find the area of a regular octagon?
circle has 360 degrees. the octagon forms 8 triangles intersecting at the center of this circle. divide 360 by 8 and you get 45 degrees for the central angle of each of these triangles. we will work with one of these triangles to get the area of it.
Are there regular polygons inscribed to a circle calculator?

Where to plant polygons inscribed to a circle?
I want to kill the grass in this ~ 616 sq. ft. area and plant dwarf fruit trees/shrubs with a ring of short perennials on the outside of the circle so it is delineated from the rest of the yard. Planting at the vertices of a polygon inscribed inside a circle is the best use of this area.
How can you tell the diameter of an inscribed circle?
Hence the diameter of the inscribed circle is the width of octagon. If you know the side lengths of a regular octagon then the diameter can be found using the method that I used in the answer to a previous question.
