Strand: GEOMETRY - Geometric Measurement and Dimension (G.GMD)
Explain volume formulas and use them to solve problems
(Standards G.GMD.1, 3).
Standard G.GMD.1
Give an informal argument for the formulas for the circumference of a circle, area of a circle, volume of a cylinder, pyramid, and cone. Informal arguments for area formulas can make use of the way in which area scale under similarity transformations: when one figure in the plane results from another by applying a similarity transformation with scale factor k, its area is k2 times the area of the first. Use dissection arguments, Cavalieri's principle, and informal limit arguments.
-
Area of a circle
This purpose of this task is to develop an understanding of the formula for the area of the circle.
-
Calculating Volumes of Compound Objects
This lesson unit is intended to help educators assess how well students solve problems involving measurement.
-
Circle Problems - Radius, Diameter, Circumference and Area
This lesson asks students to calculate problems involving the radius, diameter, circumference and area of circles.
-
Cylinders and Prisms
Students will look at prisms and cylinders and measure their surface areas and volumes in this lesson.

Module 7: Circles from a Geometric Perspective - Student Edition (Math 2)
The Mathematics Vision Project, Secondary Math Two Module 7, Circles: A Geometric Perspective, is composed of four learning cycles. In the first learning cycle, students use rotations and perpendicular bisectors to find the center of a circle. The second learning cycle in Module 7 builds on the circle relationships that students have learned so far in the module to develop a formula for the perimeter and area of a regular polygon. The third learning cycle addresses relationships among central angles, radii, arcs, and sectors. Students calculate arc length and the area of a sector. The final learning cycle in Module 7 is an intuitive approach to volume of prisms, pyramids, and cylinders.

Volume formulas for cylinders and prisms
The goal of this task is to establish formulas for volumes of right prisms and cylinders.
-
Volume of a Special Pyramid
The goal of this task is to calculate the volume of a particular pyramid with square base, which is easily reasoned by viewing it as one sixth of a cube.
