Lesson 3: Finding SA for Cylinder and Cone

This week, I have learned how to find the SA (Surface area) of a Cylinder and a Cone. It requires to remember formula and practice to put numbers in the formula. SA of Cylinder and Pyramid Before we start to calculate to find the SA, we need to learn the formula.  If you remember a wrong formula, not only you will end up having a wrong answer, but also wasting … Continue reading Lesson 3: Finding SA for Cylinder and Cone

Lesson 2: Multiplying and Dividing Power

This week, I have learned how to multiply and divide powers and how to solve negative exponent. It took time to understand but practicing many times lead me to get better. Multiply Powers When multiplying powers we must first learn some vocabularies, such as power, base, and exponent. The power is a number written in exponential form. Example: . This is a power. A base and the exponent consists in the power Example: . The … Continue reading Lesson 2: Multiplying and Dividing Power
