1. The figure shows two identical semicircles and two identical quarter circles in a rectangle. Find the area of the shaded part. (Take π=22/7)
The area of the shaded part
rectangle area - 3/4 circle area
[tex](l \times b) - ( \frac{3}{4} \times \pi \times r \times r) \\ (14 \times 10 \frac{1}{2} ) - ( \frac{3}{4} \times \frac{22}{7} \times 7 \times 7) \\ 147 - 115,5 \\ 31,5 \: {cm}^{2} [/tex]

5. The figure is made up of a rectangle, four identical quarter circles and two identical semicircles. Find its perimeter and area ( take π=22/7)
Jawaban:
Area=6202 cm2 Perimeter = 420 cm
Penjelasan dengan langkah-langkah:
Area quadrant = 22/7 x 28 x 28=2464 cm2
Area semicircle= 22/7 x 21 x21=1386 cm2
Area rectangle=56x42=2352 cm2
Total Area=2464+1386+2352=6202 cm2
Perimeter quadrant= 22/7×56=176 cm
Perimeter Semi circle= 22/7 x 42=136 cm
28x4=112 cm
176+132+112=420 cm
6. The figure is made up of a rectangle, four identical quarter circles anf two identical semicricles. Find its perimeter and area
JawabanArea
we divide the shape into 3
Build 1 = Rectangle
[tex]l = p \times l[/tex]
[tex]l = 56 \times 42[/tex]
[tex]l = 2352 \: {cm}^{2} [/tex]
Build 2 = two identical semicricles
[tex]l = \frac{1}{4} \times \pi \times {d}^{2} [/tex]
[tex]l = \frac{1}{4} \times \frac{22}{7} \times 42 \times 42[/tex]
[tex]l = 1386 \: {cm}^{2} [/tex]
Build 3 = four identical quarter circles
[tex]l = \pi {r}^{2} [/tex]
[tex]l = \frac{22}{7} \times {28}^{2} [/tex]
[tex]l = 2464 \: {cm}^{2} [/tex]
we add the three shapes
[tex]2464 + 1386 + 2352 = 6202 \: {cm}^{2} [/tex]
[tex]area = 6202 \: {cm}^{2} [/tex]
Perimeterfor four quarter circles
¼×4×2×π×r
2×π×r = 2×22/7×28 = 176 cm
For two semicircles
½×2×2×π×r
2×π×r = 2×22/7×21 = 132 cm
we add the two shapes
132 + 176 = 308 cm
Perimeter = 308 cmSorry if wrong.
Sorry I did not translate well
I only know that.

Cara :
setengah lingkaran bisa digabung dengan 2 seperempat lingkaran menjadi satu lingkaran, maka :
diameter lingkaran = 28 cm
jari - jari = 28 / 2 = 14 cm
Luas lingkaran = π × r²
= 22/7 × 14 × 14
= 616 cm²

13. The figure is made up of a rectangle, four identical quarter circles anf two identical semicricles. Find its perimeter and area (take phi 22/7)
Penjelasan dengan langkah-langkah:
keliling = ( π × d ) + ( π × d)
= (22/7 × 42 ) + ( 22/7 × 56 )
= 132 + 176
= 308 m
luas =
- luas lingkaran 1
= π × r²
= 22/7 × 28²
= 22/7 × 784
= 2.464 m²
-luas lingkaran 2
= π × r²
= 22/7 × 21²
= 22/7 × 441
= 1.386 m²
- luas persegi panjang
= p × l
= 56 × 42
= 1.092 m²
luas keseluruhan :
= 2.464 + 1.386 + 1.092
= 4942 m²

15. Mrs Kim buys 60 balls for $700. There are red balls and white balls. Red balls cost $11 each and white balls cost $13 each. How many balls of each colour has she bought?
Jawab:
x=11
y=13
ax + by=700
a + b=60
11a + 13b=700
11a=700 - 13b
a=700/11 - 13/11b
700/11 - 13/11b + b=60
700/11 - 2/11b=60
700 - 2b=660
-2b=660 - 700
=-40
b=20
11a + 13(20)=700
11a + 260=700
11a=700 - 260
=440
a=40
So, Mrs Kim bought 40 red balls and 20 white balls.
Semoga membantu dan bermanfaat :)

16. Two identical bowling balls are placed 1.00m apart. The gravitational force between the bowling balls is 3.084 × 10–⁹ N. a. Find the mass of a bowling ball. b. Compare the weight of the first ball with the gravitational force exerted on it by the second ball.
r = 1 m
F = 3,084 x 10⁻⁹ N
massa sama, m₁ = m₂ = m
a. Massa bola
F = G.m₁.m₂/r²
F = Gm²/r²
m² = Fr²/G
m² = 3,084 x 10⁻⁹.1²/6,674x10⁻¹¹
m² = 0,462 x 10²
m ≅ 6,8 kg
b.
Berat : w = mg = 6,8 x 10 = 68 N
weight >>>> gravitational force
