GEO-02 · Geometry and Trigonometry

Volume and surface area

Area, volume, and coordinate geometry · Stage 2

01 · Key idea

Multiply the area of the circular base by height.

Useful ruleV=Bh; cylinder=πr²h

Build on: GEO-01

02 · Worked example

Find the volume of a cylinder with radius 2 and height 5.

This teaching example is original and is not an official SAT question.

Reasoning

V=πr²h=π(2²)(5)=20π.

Answer

20π cubic units

03 · Next step

Practice questions remain in English, as on the SAT.
