Find the missing dimensions for each three-dimensional figure to the nearest tenth given the volume and other dimensions.
I'm not understanding the cones too much.
r=5in., v = 487in.3 How do I work it, given only the radius

pie r squared times v
you are missing the height, h
Volume of cone = (1/3)πr^2h
487 = (1/3)π(25)h
h = 487(3)/(25π) = appr. 18.6 in
