Best Answer

The regular nonagon will consist of 9 congruent isosceles triangles with base angles of 70 degrees and an apex angle of 40 degrees.

Its 2 equal sides: square root of 385.6367484*2/sin(40)*9 = 11.6952176 cm

Its base: sin(40)*11.6952176/sin(70) = 8 cm

Perimeter: 9*8 = 72 cm

Q: What is the perimeter of a regular nonagon that has an area of 395.6367484 square cm?

The regular nonagon will have 9 isosceles triangles each with 2 equal sides of 58.476088 and an apex angle of 40 degrees. Area: 0.5*58.476088^2 *sin(40)*9 = 9891 square cm rounded to the nearest whole number

Area of a nonagon with a circumradius of 2 units is 11.57 square units.

The regular nonagon will have 9 congruent isosceles triangles each with two equal sides of 13.1571198cm and two equal angles of 70 degrees with a base of 9cm opposite apex angle of 40 degrees. Area of triangle: 0.5*13.1571198^2 *sin(40)*9 = 500.7277596 square cm

The area of a regular hexagon with a 24-inch perimeter is about 41.57 square inches.

Obtuse. All regular polygons with more than 4 sides are obtuse-angled. Why? Think about a square...

A "regular quadrilateral" is a square. The word "radius" isn't used for squares (or polygons in general). To get the length of a side, divide the perimeter by 4. To get the diagonal of a square, multiply the length of a side by the square root of 2.

A regular quadrilateral is a square. As to the measure, the answer depends on the measure of WHAT? An angle, a side, the diagonal, area, perimeter, etc.
