Week 6 in Math 10

What I learned in math 10 class in this week is about formulas of geometric figures using the measurements that we learned last week. How we can find the surface area of a cone is we have to find two parts, the side, and the base.

The base is π×r2  and the side is π×r×s we have to combine them. So, the formula for the surface area of a cone is πr2+πrs.

The formula for the volume of a cone is easier than the surface area, it is just similar to the volume of a cylinder. Just multiplying 1/3 on the formula for the volume of a cylinder, because the same based cylinder is 3 times by the same based cone. So, the formula for the volume of a cone is 1/3×(area of a base=πr2)×height

Week 5 in Math 10

What I learned in math class in the fifth week is about the measurement. It even starts measurement unit, so we learned about the basic measurement this week. There are a lot of units, for examples, meter(m) and liter (L), and it can get other definition if we add some alphabet on the measurement.

The positive exponent measurements are da, h, and k. da means ×10, h means ×100, and k means ×1,000. There are even negative exponent measurements that are d, c, and m. d means ×1/10. c means ×1/100. m means ×1/1,000. The measurements are memorized by king henry d(a)oesn’t drink chocolate milk.

There are even bigger and smaller exponent measurements. M means ×1,000,000. G means ×1,000,000,000. µ means ×1/1,000,000. n means ×1/1,000,000,000
