Soal Matematika Kelas 6 Sd Semester Quiz

Explanation
The given options are numbers, and the question asks for the "luas bangun di samping" (area of the adjacent shape). However, there is no information given about the shape or any calculations to determine the area. Therefore, without any context or additional information, it is not possible to provide an explanation for the answer 184.

Explanation
The correct answer is 6028,8. This is because the question asks for the volume of the cylinder, and the given answer is a numerical value that represents the volume.

Explanation
Sani visits her grandmother every 6 days, Deni visits her every 12 days, and Aisya visits her every 24 days. In order for all of them to visit their grandmother together, they need to find the least common multiple of their visitation days. The least common multiple of 6, 12, and 24 is 24. Therefore, they will all visit their grandmother together every 24 days.

Explanation
To find the dimensions of the cube-shaped pond with a volume of 3.375 dm^3, we need to find the side length of the cube. Since the volume of a cube is given by the formula V = s^3, where s is the side length, we can rearrange the formula to solve for s. Taking the cube root of 3.375, we find that s = 1.5 dm. Therefore, the length, width, and height of the pond should be 1.5 dm each, which is equivalent to 15 cm.

Explanation
Bu Esti harus membayar Rp250.000 setiap kali mengangsur karena itu adalah jumlah bunga yang dikenakan. Dengan kata lain, setiap kali Bu Esti mengangsur, ia harus membayar Rp250.000 sebagai bunga tambahan dari harga komputer sebesar Rp3.000.000. Jumlah ini akan dibayarkan selama 8 kali angsuran sehingga total bunga yang harus dibayar Bu Esti adalah Rp250.000 x 8 = Rp2.000.000.

Explanation
Pak Ari akan mengisi kolam renang dengan air dari 2 buah keran. Debit air setiap keran adalah 5 liter per detik. Kolam renang memiliki volume panjang x lebar x tinggi, yaitu 25m x 5m x 2m = 250m^3. Untuk mengisi kolam renang tersebut, kita perlu mengubah volume menjadi liter, yaitu 250m^3 x 1000L/m^3 = 250,000L. Debit air dari kedua keran adalah 5L/detik x 2 = 10L/detik. Waktu yang diperlukan untuk mengisi kolam renang adalah volume kolam renang dibagi dengan debit air, yaitu 250,000L / 10L/detik = 25,000 detik.

Explanation
The given figure is a combination of a semicircle, a square, and a triangle. The diameter of the semicircle is 28 dm, which means the radius is 14 dm. The area of the semicircle is (1/2) * π * r^2, which is (1/2) * π * 14^2 = 308π dm^2. The area of the square is 28 dm * 28 dm = 784 dm^2. The area of the triangle is (1/2) * base * height, which is (1/2) * 24 dm * 28 dm = 336 dm^2. Therefore, the total area of the combined figure is 308π + 784 + 336 = 1428 dm^2.

Explanation
Based on the diagram above, it can be observed that the number of students who play soccer is represented by the bar that reaches the value of 20. Therefore, the correct answer is 20 students.

Explanation
The given information states that the ratio of the length to the width of a rectangle is 5:3. If the perimeter of the rectangle is 8 meters, we can determine the width by dividing the perimeter by the sum of the ratio's terms (5+3). Therefore, the width of the rectangle is 1.5 meters.

Explanation
The average of Anwar's math test scores for the first semester is 75. This is calculated by adding up all the test scores (85+70+65+80+75+75) and then dividing the sum by the number of scores (6).
