Use Pythagorean theorem Since the diagram shows that the diameter of the pyramid is 18.2cm you divide it by 2 to get the radius 9.1 Now you know the two parts of the triangle so you can use Pythagorean theorem to solve Slant height is also same as hypotenuse... So it would be ..... 13.6^2 + 9.1^2 = x^2 184.96 {if rounded 185}+ 82.81 {if rounded 83} = x^2 268 = x^2 X is approximately 16.4
