What is the formula to find the side length of a pentagon when the radius and apothem are known?

• Side length = Radius * cos(Angle)

• Side length = Radius * sin(Angle)

• Side length = 2 * Radius * tan(Angle / 2)

• Side length = 2 * Radius * sin(Angle / 2)

How is the height of a pyramid calculated using the Pythagorean theorem?

• Height = √(Slant Height² - Base Length²)

• Height = Slant Height + Base Length

• Height = Slant Height² - Base Length²

• Height = √(Slant Height² + Base Length²)
