Question

what 3 dimensional shape will be created by spinning (rotating ) the right triangle below around the y axis? triangular prism cylinder sphere cone

Explanation:

Step1: Recall 3 - D shape formation

When a right - triangle is rotated about one of its legs (in this case, the y - axis which is one of the legs of the right - triangle), a cone is formed. The leg about which it is rotated becomes the height of the cone, and the other leg becomes the radius of the base of the cone.

Answer:

D. Cone
