A square pyramid is intersected by a plane passing through the vertex and perpendicular to the base. Which two-dimensional shape describes this cross section?

• square

• triangle

• pentagon

As shown in the diagram below, right triangle ABC has side lengths of 8 and 15. If the triangle is continuously rotated about AC, the resulting figure will be:

• a right cone with a radius of 15 and a height of 8

• a right cone with a radius of 8 and a height of 15

• a right cylinder with a radius of 15 and a height of 8

• a right cylinder with a radius of 8 and a height of 15
