1. a box weighing 300 newton is swung as shown in the figure. the amount of F required to pull the box is.....N
weight= force
if W is 300n. then F is 300N.
so the power to pull the box ia 300N
2. what is the pythagorean theorem?
Jawab:
In mathematics, the Pythagoeran theorem, also known as the Pythagorean theorem, is the fundamental relationship in Euclidean geometry between the three sides of a right triangle. This tells us that the area of a square whose side is the hypotenuse equals the area of the squares on the other two sides.
Ppppppppp
3. 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
4. The figure is not drawn to scale. Find the area of the shaded triangle.
Jawaban:
484
Penjelasan dengan langkah-langkah:
Area of triangle = Base x Height
= 22 x 22
= 484
So, the area of the shaded triangle is 484
5. The figure is not drawn to scale. What is the shaded area?
Penjelasan dengan langkah-langkah:
triangle 1
= 1/2 x a x t
= 1/2 x 10 x 12
= 60 cm2
triangle 2
= 1/2 x a x t
= 1/2 x 8 x 10
= 40 cm2
triangle 1 - triangle 2
= 60 cm2 - 40 cm2
= 20 cm2

8. 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
9. a circular hoop of radius 16 cm is cut into 4 equal pieces and then rearanged to form the figure shown. find the perimeter of the figure, giving your answer correct to 1 decimal places
perimeter of circular
= 2πr
= 2 x 3,14 x 16
= 100,48
= 100,5
I'm sorry, if the answer ia false

11. The figure is made up of a square and trapezium. The perimeter of the figure is 60 cm. Find the area of the figure. Use the steps.
Jawab:
The area of the figure is 188 cm².
Penjelasan dengan langkah-langkah:
Form that figure, we know that A and C are both squares. Therefore, the length of the rightmost side of the figure is 8 cm.
Let s be the length of C’s sides.
Given that the perimeter of the figure is 60 cm, we can get:
(14 + 2×8 + 3s) cm = 60 cm
⇔ 14 + 16 + 3s = 60
⇔ 30 + 3s = 60
⇔ 3s = 60 – 30
⇔ 3s = 30
⇔ s = 30/3
⇔ s = 10 cm
Let A be the area of the figure, we can find:
A = the sum of all areas
⇔ A = area of square A + area of trapezium
⇔ A = s² + ½(base+top)×height
⇔ A = 10² + ½(14+8)×8
⇔ A = 100 + 11×8
⇔ A = 100 + 88
⇔ A = 188 cm²
CONCLUSION∴ The area of the figure is 188 cm².

16. 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]

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
20. Rectangle A overlaps Square B as shown. The ratio of the area of Rectangle A to the shaded area to the area of Square B is 6:1:4 The area of Rectangle A is 36 cm2. Find the area of the whole figure.
Ratio of the area of Rectangle A =
6 units
6 units = 36 cm2
1 unit = 36 ÷ 6 = 6 cm2
Ratio of total area = 6 + 1 + 4 = 11 units
11 units = 11 x 6 = 66 cm2
The area of the whole figure is 66 cm2.
