What is the area of a regular nonagon that has a perimeter of 360 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
What are the measurements of interior angles of a regular nonagon?
The sum of the interior angles of a nonagon is (9 - 2) x 180o = 7 x 180o = 1260o In a regular nonagon, each interior angle is 1260o ÷ 9 = 140o
What is the area of a regular nonagon having a perimeter of 81cm?
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
How do you find the diametre if you have the area?
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
What is the length of each side of a regular nonagon if it has an apothem of 25 and a area of 2025?
Area of a regular polygon = 1/2(apothem)(perimeter) 2025 = 1/2(25)(perimeter), so the perimeter = 2025 divided by 25/2. Perimeter = 162 Side length = 162/9 Side length = 18
What is the area of a regular nonagon with side 3 cm?
55.6 cm^2 approx.

How do you find the area of a square using the radius and the apothem?
For a SQUARE, the area is (2r)2 because the length and width are the same. The apothem (radius) is used to find the area of other regular polygons.
What is the area of a regular nonagon having a perimeter of 81cm?
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
How do you find the diametre if you have the area?
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
How do you get circumference from area of a circle?
Area = π × radius² → radius² = area/π → radius = √(area/π) Circumference = 2 × π × radius = 2 × π × √(area/π) = √(2² × π² × area/π) = √(4 × π × area)
How do you find the diameter of a circle if they give you the area?
Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)
What is the length of each side of a regular nonagon if it has an apothem of 25 and a area of 2025?
Area of a regular polygon = 1/2(apothem)(perimeter) 2025 = 1/2(25)(perimeter), so the perimeter = 2025 divided by 25/2. Perimeter = 162 Side length = 162/9 Side length = 18
How do you find the area of a circle that has a diameter of 4. 2?
2*radius=diametre radius=2.1 Area=pi*(radius)^2 Area=3.1428*2.1*2.1 Area=13.86
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
The measure of one interior angle of a regular nonagon?
The measure of an interior angle of a regular nonagon is 140o. This is found in any polygon by multiplying 2 less than the number of sides by 180o and then dividing the product by the number of sides. A nonagon interior angle is then 7 x 180o/9 = 140o.
