This is the third section of Chapter 11: Geometry and Measurement Relationships. This section’s learning goal is to “Develop and apply a formula for calculating the volume of a cylinder.” After that, we list the volume formula for spheres, square-based pyramids, rectangular prisms, isoceles triangular prisms and cones. 135 more words

#### 11.2.2: Surface Area of Platonic Solids

This is an extension of section 11.2, “Surface Area of a Cylinder”. Students developed formulas for finding the surface area of various platonic solids: cylinders, spheres, square-based pyramids, rectangular prisms and cones. 33 more words

#### 11.2.1: Surface Area of a Cylinder

Section 11.2, “Surface Area of a Cylinder”, is the second section of chapter 11, “Geometry and Measurement Relationships”. The learning goal for this section is to “Develop and apply a formula for calculating the surface area of a cylinder”, and as such, is where we really start to talk about cylinders in particular, rather than area and surface area in general. 561 more words
