Half full of water by volume. How deep is the water in the cone if the height is 16 cm and base is 12 cm

  8∛4 ≈ 12.70 . . . . cm deep

Step-by-step explanation:

The ratio of volumes of similar cones is the cube of the ratio of their linear dimensions. That means the height of a cone with 1/2 the volume will be ...

  ∛(1/2)

times the height of the full cone.

The water will be ...

  (16 cm)(∛(1/2)) = 8∛4 ≈ 12.70 . . . . cm deep

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
