1/2×M2= -1
M2= -2
Volume for a cone is 1/3 pi * r^2*h, where r is radius and h is height. We have diameter = 1/2 radius. Thus, radius = 1.5in. We also have volume is 12 in. Using formula for volume of a cone and plugging in what we know, we have 12 = 1/3*pi*(1.5)^2*h, were solving for h. To get, h= (12*3)/(pi*(1.5)^2), which is approximately 5.0931in, 5 inches

Answer:
sqrt(2)/2
Step-by-step explanation:
Sin(135) = sin(180-135) = sin(45)
= 1/sqrt(2) or sqrt(2)/2
sqrt: square root
