1. The circular portions of the following figures are semicircles. Find the perimeter and area of each of the following figures.
Penjelasan dengan langkah-langkah:
(a)
Luas = 3x5/2 + 3,14 x 2²/2 = 7,5 + 6,28 = 13,78 m²
Keliling = 3+5 + 3,14x2 = 8 + 6,28 = 14,28 m
(b) Luas = 3,14 x 9/2 + 3,14 x 4,5
= 3,14 x 9 = 28,26 cm²
Keliling = 3,14 x 18/2 + 3,14 x 9
= 3,14 x 18
= 56,52 cm
Penjelasan dengan langkah-langkah:
a.
Luas = 3 × 5/2 + 3,14 × 2²/2 = 7,5 + 6,28 = 13,78 m²
keliling = 3 + 5 + 3,14 × 2 = 8 + 6,28 = 14,28 m
b.
Luas = 3,14 × 9/2 + 3,14 × 4,5 = 3,14 × 9 = 28,26 m²
keliling = 3,14 × 18/2 + 3,14 × 9 = 3,14 × 18 = 56,52 cm

9. For each of the following figures, find the area of the blue region(s).
c. 45 cm²
d. 150,96 cm²
Penjelasan dengan langkah-langkah:
c. L = L.trapesium - L.segitiga
= 1/2 x (9+17) x 12 - 1/2 x 17 x 6
= 1/2 x 16 x 12 - 51
= 96 - 51
= 45 cm²
d. L = L.jajaran genjang - L.lingkaran
= 12 x 22 - 3,14 x 6 x 6
= 264 - 113,04
= 150,96 cm²

11. The circular positions of the following figures are semicircles.for each of the following figures find its perimetere and area kerjain A,B,and C
Penjelasan dengan langkah-langkah:
a)
keliling lingkaran =
[tex]2 \pi r[/tex]
[tex] = 2 \times \frac{22}{7} \times \frac{21}{2} \\ = 66[/tex]
kelililig total = 66 + 2×(36-21)
= 66 + 30 = 96cm
parimeter = 96 cm
luas = luas lingkaran + luas persegi
[tex] = \frac{22}{7} \times {21}^{2} + {(36 - 21)}^{2} \\ = 1386 + 225 \\ = 1611[/tex]
luas = 1611 cm^2
area = 1611 cm^2

when you want to write article/journal/research paper, you have to read a lot of books as references and you may take the notes of the expert's opinion you must remember the rules to avoid plagiarism:
1. if you take all the the expert's opinion without adding your idea, you must give a quotation mark (".."), the year and page. For example: "Poetry was composed of comedy, tragedy, and epic" (Aristotle, 1880:24)
.
2. if you just take the main point of the expert's idea and mixing with your idea, no need to put in ".." For example: Approve to Aristotle we know that poetry is an art of comedy, tragedy, and epic which contains a very poetic choice of words. or you can write like this one: Aristotle suggested that poetry was composed of comedy, tragedy, and epic (remember to use simple past tense form if you take the opinion with your fewer idea)
usually when we want to rewrite the expert opinion use simple past:
Aristotle suggested that..
Alexander said that..
Chomsky approved that
Soekarno agreed that..

16. Find the area of the shaded triangle. write down each step and give your answers in the correct units.harus cari area segitiga nya
Rectangle
Area = 70 × 45
= 3.150 m²
Long triangle
Area = ½ × 70 × 45
= 35 × 45
= 1.575 m²
Short triangle
Area = ½ × 32 × 45
= 16 × 45
= 720 m²
Shaded triangle
Area = 3.150 - 1.575 - 720 = 855 m²
