Part II ( meaning and application of my difficult word)
1. Two sphere or more are concentric if the both of them in a same center of sphere
- sphere = bola
- concentric = sepusat
2. A circle have radius of 5 cm, so the circumference of that circle 220/7 cm
- radius = jari-jari
- circumference = keliling
3. The solution of linear equality one variable only one problem solving. So, if there is a equality :
X + 5 = 6
<=> x = 1
So, the set solve that linear equality one variable is {1}
- equality = persamaan
- set solve = himpunan penyelesaian
4. Integers are the number of whole number and negative number
- integer = bilangan bulat
- whole number = bilangan cacah
5. Addition on integers can be interpreted as a directed distance
- Addition = penjumlahan
6. Subtraction operation on integers is to find out the difference between two integers. We can use a number line to indicate subtraction
- subtraction = pengurangan atau selisih
- number line = garis bilangan
7. The form of a/b where a and b are integers, a and b are not equal as with 0. a is called the numerator and b is called denominator
- numerator = pembilang
- denominator = penyebut
8. A isosceles triangle have two of same edges
- isosceles triangle = segitiga sama kaki
- edge = sisi
9. A cube have twelve of lateral edges
- lateral edge = rusuk
10. One of the angles of right angle triangle have 90
- right angle triangle = segitiga siku-siku
11. A tube with 7 cm of radius and 4 cm of altitude have 176 cm of lateral surface
- altitude = tinggi silinder
- lateral surface = luas selimut
