The sum of the interior angles of a polygon is given by (n-2) * 180 degrees, where n is the number of sides. For a hexagon, (6-2) * 180 = 720 degrees.
The area of a circle is calculated using the formula πr^2, where r is the radius.
The diagonal can be found using the Pythagorean theorem: √(3^2 + 4^2) = √(9 + 16) = √25 = 5 cm.
Similar triangles have the same shape and angles but their side lengths are proportional.
The perimeter of an equilateral triangle is 3 times the side length. So, 3 * 5 cm = 15 cm.
The volume of a sphere is calculated using the formula 4/3πr^3, where r is the radius.
The sum of the angles in a triangle is always 180 degrees. So, 180 - (35 + 55) = 90 degrees.

The area of a triangle is calculated using the formula (base * height) / 2. So, (8 cm * 5 cm) / 2 = 20 cm^2.
In a parallelogram, opposite angles are equal and opposite sides are parallel and equal in length.
The surface area of a cylinder is given by the formula 2πr(r + h), where r is the radius and h is the height.
The hypotenuse can be found using the Pythagorean theorem: √(6^2 + 8^2) = √(36 + 64) = √100 = 10 cm.
