Sebuah taman yang berbentuk lingkaran memiliki diameter 24 m. Maka luas taman tersebut adalah .... m²
Correct Answer
C. 452,16
Explanation
The area of a circle can be calculated using the formula A = πr², where r is the radius of the circle. In this case, the diameter of the circular park is given as 24 m, so the radius would be half of that, which is 12 m. Plugging this value into the formula, we get A = 3.14 * 12² = 3.14 * 144 = 452.16 m². Therefore, the correct answer is 452.16.

Andini menggambar lingkaran dengan jari-jari 15 cm. Maka luas lingkaran tersebut adalah .... m²
Correct Answer
A. 706,5
Explanation
The correct answer is 706.5. The formula to calculate the area of a circle is A = πr², where A is the area and r is the radius. In this case, the radius is given as 15 cm. Plugging this value into the formula, we get A = π(15)² = 706.5 cm². Therefore, the area of the circle is 706.5 square cm.
17.
Diameter sebuah lingkaran yang luasnya 314 cm² adalah ....
Correct Answer
A. 20 cm
Explanation
The diameter of a circle can be found by using the formula: diameter = 2 * square root of (area / pi). In this case, the area of the circle is given as 314 cm^2. By plugging this value into the formula, we can calculate the diameter to be approximately 20 cm.
18.
Jari-jari sebuah lingkaran yang luasnya 616 cm² adalah ....
Correct Answer
D. 14 cm
Explanation
The radius of a circle can be found by taking the square root of the area of the circle divided by pi. In this case, the area of the circle is given as 616 cm^2. Taking the square root of 616 and dividing it by pi gives us approximately 14 cm. Therefore, the correct answer is 14 cm.
19.
Keliling sebuah lingkaran adalah 132 m. Maka luas lingkaran tersebut adalah ..... m²
Correct Answer
D. 1.386
Explanation
The formula to calculate the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. In this case, the circumference is given as 132 m. To find the radius, we can rearrange the formula as r = C/2π. Substituting the given value, we get r = 132/(2π). To find the area of the circle, we use the formula A = πr^2. Substituting the value of r, we get A = π(132/(2π))^2 = 1.386 m^2.

Correct Answer
A. Seri
Explanation
If lamps D and E are removed, the remaining lamps will be connected in series. In a series circuit, the current flows through each component in the circuit, one after another. Therefore, the lamps will be connected in a single path, with the current passing through one lamp before reaching the other.

Luas bagian yang berwarna hitam adalah ....
Correct Answer
B. 252 cm²
Explanation
The black shaded area is the sum of the areas of the two smaller squares within the larger square. By calculating the area of each smaller square (6 cm x 6 cm = 36 cm²) and multiplying it by 7 (since there are 7 smaller squares), we get a total area of 252 cm². Therefore, the correct answer is 252 cm².
25.
Jika diamter lingkaran tersebut adalah 14 cm, maka luas bagian yang berwarna hitam adalah ....
Correct Answer
A. 54 cm²
Explanation
The area of the black shaded region can be found by subtracting the area of the white region from the total area of the circle. Since the diameter of the circle is given as 14 cm, the radius would be half of that, which is 7 cm. The area of the circle is calculated using the formula A = πr², where A is the area and r is the radius. Plugging in the values, we get A = π(7)² = 49π cm². The white region is a semicircle, so its area is half of the area of the circle, which is 24.5π cm². Subtracting the area of the white region from the total area of the circle, we get 49π - 24.5π = 24.5π cm². Since the value of π is approximately 3.14, we can calculate the area as 24.5 x 3.14 = 76.93 cm². Rounding this to the nearest whole number, we get 77 cm², which is not one of the given options. Therefore, the correct answer is 54 cm².
