Since the side lengths of the hexagon are all equal, it is a 'regular' hexagon. Therefore all the interior angles of the hexagon are equal. To find the sum of the interior angles of the regular …

The cross section of a cone is a right triangle, if you know that you can use the Pythagorean theorem. …
The formula for the lateral surface area of a cone is the radius multiplied by the slant height multiplied by pi. LSA = rlπ You can move parts of that equation around depending on the information …
The expected answer would be 4π/7, but that is not the answer since 4π/7 is outside the acceptable range of [−π/2,π/2] for the arcsin function. If you took the arcsin of the sin of an angle within the …

An isosceles triangle is a triangle with two sides that are equal (congruent). An equilateral (three equal sides) triangle is also isosceles, but an isosceles triangle is not necessarily …
Assuming it is a right circular cone, here's the equation for the volume and two ways to think about it. For the cone, you have the height, radius, and slant height. pi r^2 is the area of a circle, so …
