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

  • Math -

    pie r squared times v

  • Math -

    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
