A cone shaped hat is shown: A cone is shown with slant height 14 cm and radius 6.2 cm. The unknown height is labeled with a question mark, and the line joining the tip of the cone to the base is perpendicular to the base. What is the approximate height of the hat? 2.79 centimeters because height = Square root of the difference of 14 and 6.2 4.49 centimeters, because height = Square root of the sum of 14 and 6.2 12.55 centimeters, because height = Square root of the difference of squares of 14 and 6.2 15.31 centimeters, because height = Square root of the sum of the squares of 14 and 6.2

we will use the pythagorean theorem to find x a^2 + b^2 = c^2 x^2 + 6.2^2 = 14^2 x^2 + 38.44 = 196 x^2 + 38.44 - 38.44 = 196 - 38.44 x^2 + 0 = 157.56 x^2 = 157.56 x = ???

you don't divide both sides by 2
jim_thompson5910
  • jim_thompson5910
you apply the square root to both sides
