Boot Camp Day 1: Measurement in 2-Dimensions

Which of the cross sections described would result in a rectangle with a height of inches (in.)?

• A horizontal cross section through the center of a sphere with a radius of 4 in.

• A horizontal cross section through the center of a cone with a radius of 4 in. and a height of 8 in.

• A vertical cross section through the center of a cone with a radius of 4 in. and a height of 4 in.

• A vertical cross section through the center of a cylinder with a radius of 4 in. and a height of 4 in.

A cone is shown. The radius of the base of the cone is 14 cm. and the cone’s height is 24cm. Complete the description of the cross section if the horizontal plane is located at a height of 12cm. The cross section is a [Drop Down 1] with a [Drop Down 2] of [Drop Down 3] .

The answer to 'Drop Down 1' is:

• triangle

• circle

• rectangle

• oval
