What is the ratio of the volumes? 2.If the hypotenuse in a 30-60-90 triangle is 18, then the length of the short leg is? a. 12.73 b. 10.39 c. 36 d. 9Answer by Nate(3500)   (Show Source): You can put this solution on YOUR website!1.The ratio of the surface area of two pyramids is 9:49. What is the ratio of the volumes? Ratio of Surface Areas: a^2 : b^2 or 9 : 49 a = 3 b = 7 Ratio of Volumes: a^3 : b^3 or 27 : 343 2.If the hypotenuse in a 30-60-90 triangle is 18, then the length of the short leg is? a. 12.73 b. 10.39 c. 36 d. 9 The shorter length is opposite the 30 degree angle ... geometrical theory states that the length of that leg is half the hypotenuse. 1/2 * 18 = 9 (d.)
