1. A figure is made up of a rectangle and a semicircle as shown in the diagram below. what is the area of the figure?
Jawab:
Area itu bahasa inggris dari Luas, maka
Area of square = S x S
= 7 x 7
= 49 cm²
Radius = Diameter / 2
= 7 / 2
= 3.5 cm
Area of [tex]\frac{1}{2}[/tex] circle = [tex]\frac{1}{2}[/tex] x [tex]\pi[/tex] x r²
= [tex]\frac{1}{2}[/tex] x [tex]\frac{22}{7}[/tex] x 3.5²
= 19.25 cm²
Are of the figure = 49 + 19.25 = 68.25 cm²
Penjelasan:
phi [tex](\pi )[/tex] untuk [tex]\frac{22}{7}[/tex] digunakan apabila jari-jari/radius berkelipatan 7, sedangkan
phi untuk 3.14 digunakan apabila jari-jari/radius tidak berkelipatan 7

5. figure B is made up of four identical right angled triangles as shown in figure A. Four times the perimeter of figure A is 96cm. The perimeter of Figure B is 48cm. What is the lenght of XY?tolong dibantu sesegera mungkin ya.. thanks. #math#matematika#triangle#perimeter
Jawaban:
6 cm
Penjelasan dengan langkah-langkah:
4(Keliling gambar A) = 96 cm
Keliling gambar A = 24 cm
Gunakan tripel Pythagoras
Segitiga 3-4-5 adalah segitiga siku-siku dan kelilingnya adalah (3+4+5) cm = 12 cm
Kalau mau dapatkan segitiga siku-siku dengan kelilingnya adalah 24 cm, maka tripel Pythagorasnya adalah 6-8-10 (Cuma dikali 2). Karena XY(alas segitiga) lebih pendek daripada tinggi segitiga, maka XY = 6 cm
6. In the figure below, the value of x is..... cm

8. a piece of wire 144cm long is bent to form a semicircle as shown in the figure. find the diameter of the semicircle, giving your answer in metres.
Jawaban:
0,46 mPenjelasan dengan langkah-langkah:
A mean a piece of wire = a circumference of a semicircle
[tex]c = \pi \: d \\ 144 = 3.14 \: d \\ d = \frac{144}{3.14} \\ d = 45.86 \\ d = 46 \: cm \div 100 \\ d = 0.46 \: m[/tex]
Plz correct my answer if it's wrong .

13. in the figure below,the value of x is.... cm
6 / 18 = x / x + 16
18x = 6x + 96
18x - 6x = 96
12x = 96
x = 96/12
x = 8
14. A rectangular field is a surrounded by a concrete path as shown in the figure. The breadth of the field is x m and its length is 15 m longer than its breadth

19. A glass house is in the shape as shown in the figure . calculate total area of glass needed and calculate the volume of the glass house
Jawab:
Total Luas seluruh bangunan = L prisma segitiga + L balok
= 248 m² + 292 m² = 540 m²
Total Volume seluruh bangunan = V prisma segitiga + V balok
= 60 m³ + 336 m³ = 396 m³
Penjelasan dengan langkah-langkah:
Bangunan ini adalah gabungan dari prisma segitiga dan balok.
Diketahui :
Prisma segitiga : alas = 5 m
tinggi alas = 6 m
tinggi prisma = 11 m - 7 m = 4 m
Ditanya : L = ?
V = ?
L = 2 X Luas alas + Keliling alas + tinggi
= 2 X (1/2 X 5X6) + (5+5+6) x 4
= 2 x (15 + 16 x 4)
= 2 x 124 = 248 m²
Volume = Luas alas X tinggi
= (1/2 X 5X6) X 4
= 60 m³
Sekarang kita hitung balok.
Diketahui : p = 8 m
l = 6 m
t = 7 m
Ditanya : L = ?
V = ?
L balok = 2 (pl + pt + lt)
= 2 (8X6 + 8X7 + 6X7)
= 2 (48+56+42)
= 2 x 146 = 292 m²
Volume balok = pxlxt
= 8 X 6 X 7
= 336 m³
Total Luas seluruh bangunan = L prisma segitiga + L balok
= 248 m² + 292 m² = 540 m²
Total Volume seluruh bangunan = V prisma segitiga + V balok
= 60 m³ + 336 m³ = 396 m³
