6. 11.A sector of a circle that has radius 10 cm is 78.5 cm. What is the central angle? 12. A Wheel spun 60 times. It its diameter is 50 cm and π(Pi) = 3.14 what is the distance that the wheel reach? 13. Look at the picture! 108 If the diameter of the circle is 28 cm, what is the area of sector OABY
11. a sector of a circle that has radius 10cm is 78,5cm. What is the central angle
Answer :
the formula for the area of a circle is :
r².π (22/7 or 3,14)
10².3.14. x/360=78,5
100.3.14. x/360=78,5
314x/360=78,5
314x=360.78,5
314x=28260
x=28260:314
x=90°
pengertian
bidang lingkaran yang berjari-jari 10cm adalah 78,5cm. Berapa sudut pusatnya
Jawaban:
rumus luas lingkaran adalah:
r².π (22/7 atau 3,14)
10².3.14. x / 360 = 78,5
100.3.14. x / 360 = 78,5
314x / 360 = 78,5
314x = 360,78,5
314x = 28260
x = 28260: 314
x = 90 °
12. Wheel spin 60 times. It its diameter ia 50 cm and π(pi) =
Answer : radius = diameter:2.
r= 50:2 =25
the formula for the area of a circle is :
r².π (22/7 or 3,14)
25².3,14.60
625.188,4
117750,0
pengertian : Roda berputar 60 kali. Diameternya adalah 50 cm dan π (pi) =
Jawab: jari-jari = diameter: 2.
r = 50: 2 = 25
rumus luas lingkaran adalah:
r².π (22/7 atau 3,14)
25².3,14.60
625.188,4
117750,0
13. If the diameter of the circle ia 28 cm, what is the area sector OABY
Answer : radius = diameter:2.
r= 28:2. =14
the formula for the area of a circle is :
r².π (22/7 or 3,14)
14².22/7. 108/360
196.22/7.3/10
28.22.3/10
616.3/10
1848/10
184,8 cm²
so the area of OABY = 184.8 cm²
pengertian : Jika diameternya 28 cm maka bidang luasnya adalah OABY
Jawab: jari-jari = diameter: 2.
r = 28: 2. = 14
rumus luas lingkaran adalah:
r².π (22/7 atau 3,14)
14².22 / 7. 108/360
196.22 / 7.3 / 10
28.22.3 / 10
616,3 / 10
1848/10
184,8cm²
jadi luas OABY = 184,8cm²

Area of Frame and Picture
Area = L * W
L = 9
W = 6
Area = 9*6 = 54 in²
Area of Picture
Area = L*W
L = 6
W = 4
Area = 6 * 4
Area = 24 in²
Area of Frame
Area of Frame = Total Area - Picture Area
Area of Frame = 54 - 24
Area of Frame = 30 in²

15. 1.The diameter of a circle is 20 m, so the radius is .. 2.The circumference of a circle with the diameter of 14 cm is .... 3.The circumference of a semi circle with the diameter of 14 cm is .... 4.The radius of a circle is 28 cm. The area of a quadrant is ...
Jawab:
1. 10 m
2. 44 cm
3. 36 cm
4. 154 cm²
Penjelasan dengan langkah-langkah:
1. Radius = half diameter = 20 /2 = 10 m
2. Circumference = 2 x 22/7 x 7 cm = 44 cm
3. Circumference = diameter + half circumference = 14 + 22/7 x 7 = 36 cm
4. Area quadrant = 1/4 x 22/7 x 14 x 14 = 154 cm²
16. If a sector of a circle has an arc lenght of 2π inches and an area of 6π square inches, what is the radius of the circle?mohon bantuannya kak
terjemahan: jika juring dari sebuah lingkaran memiliki panjang busur 2π inci dan luasnya adalah 6π inci², berapa radius (jari²) dari lingkaran tsb?
jawab:
luas juring (sector's area) = 6π
panjang busur (arc length) = 2π
[tex] \frac{ \alpha }{360°} \times \pi \times 2r = 2\pi \\ \frac{ \alpha }{360°} \times 2\pi r = 2\pi \\ \frac{ \alpha }{360°} \times r = 1 \\ r = \frac{1 \times 360°}{ \alpha } = \frac{360}{ \alpha }[/tex]
[tex] \frac{ \alpha }{360°} \times \pi \times {r}^{2} = 6\pi \\ \frac{ \alpha }{360°} \times {r}^{2} = 6 \\ {r}^{2} = \frac{6 \times 360°}{ \alpha } = \frac{720}{ \alpha } [/tex]
[tex] \frac{ {r}^{2} }{r} = r \\ \frac{ \frac{720}{ \alpha }}{ \frac{360}{ \alpha } } = r \\ \frac{720}{ \alpha } \times \frac{ \alpha }{360°} = r \\ 2 = r \\ r = 2[/tex]
Catatan:
[tex] \frac{ \alpha }{360°} \times \pi \times 2r \: adalah \: rumus \: menentukan \: panjang \: busur \\ \frac{ \alpha }{360°} \times \pi \times {r}^{2} \: adalah \: rumus \: menentukan \: luas \: juring[/tex]
