the formula for the radius of any regular polygon is: r=s/(2 sin (π/n)) where r = radius, s = length of side n = number of sides (in this case 12) and of course π = 3.14 Sin is in radians.
Set up the equation and solve using the formula for area of a circle: (pi = 3.14) a = P * r-squared (substitute with known numbers) 113.04 = 3.14 * r-squared (divide both sides by pi (3.14)) 36 = r-squared (find the square root of 36 to solve for the radius) 6 = r
The ulna bone is located on the your pinky side of your arm, the radius bone is located on your thumb side of your arm. And the humerus is the bone located above your elbow. There are pics on google.
Density = mass / volume. You have the density of aluminum and the mass of the aluminum sphere. The volume of a sphere is 4/3*Pi*r^3. Therefore volume = 4/3*Pi*r^3 = mass / density. Solve for r, which is the radius of the sphere.
-- Collect all the information you know about the object whose circumference you need to find, such as its radius or diameter. -- Substitute the information you have into a mathematical formula that relates circumference to the information you have.
The volume of a tree trunk can be estimated using the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height. Given the circumference (C = 2πr), we can find the radius (r = C/(2π) = 4.5/(2π)) and then calculate the volume using V = π(4.5/(2π))^2 * 13 = approximately 134.23 cubic feet.

You can find the number of diagonals in a polygon using the formula n(n-3)/2, where n is the number of sides. Therefore an 11 sided polygon has 44 diagonals.
To find the number of diagonals in a polygon with ( n ) sides, you can use the formula ( \frac{n(n-3)}{2} ). For a 33-sided polygon, this would be ( \frac{33(33-3)}{2} = \frac{33 \times 30}{2} = 495 ). Therefore, a 33-sided polygon has 495 diagonals.

To find the sum of the interior angles of a polygon, you can use the formula ( (n - 2) \times 180 ), where ( n ) is the number of sides. For a 22-sided polygon, the calculation is ( (22 - 2) \times 180 = 20 \times 180 = 3600 ) degrees. Therefore, the sum of the interior angles in a 22-sided polygon is 3600 degrees.
Well honey, a 27-sided polygon has 27 interior angles. To find the sum of those angles, you use the formula (n-2) * 180, where n is the number of sides. So, for a 27-sided polygon, you'd have (27-2) * 180 = 4,860 degrees. Math doesn't lie, darling.
This figure is a regular 12-sided polygon. Find m<4
To find the sum of the interior angles of a polygon, you can use the formula ( (n - 2) \times 180 ) degrees, where ( n ) is the number of sides. For a 17-sided polygon, this would be ( (17 - 2) \times 180 = 15 \times 180 = 2700 ) degrees. Therefore, a 17-sided polygon has a total of 2700 degrees in its interior angles.
To find the interior angle of a 13-sided polygon (triskaidecagon), you can use the formula for the interior angle of a regular polygon: ((n - 2) \times 180° / n), where (n) is the number of sides. For a 13-sided polygon, this calculation is ((13 - 2) \times 180° / 13 = 11 \times 180° / 13 \approx 152.31°). Therefore, each interior angle of a regular 13-sided polygon is approximately 152.31 degrees.
For any n-sided regular polygon the exterior angles are 360/n degrees.
Using a protractor an 8 sided octagon angles will add up to 1080 degrees Or use the formula: (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
