🎯 Key Takeaways for quick navigation: 00:41 🔄 *A circle is a set of points on a flat surface equidistant from a fixed point called the center, represented as "P."* 01:09 📏 *The distance from the center (P) to any point on the circle is the radius (R), and if the distance is the same, it is called the radius.* 02:34 🔄 *The area inside a circle is its circumference, calculated using the formula \(2 \pi r\) or \(2 \times \frac{22}{7} \times r\).* 03:15 🔄 *There are two essential formulas for circles: the area (using \( \pi r^2 \)) and the circumference (using \(2 \pi r\) or \(2 \times \frac{22}{7} \times r\)).* 03:58 🔄 *A circular arc is a set of curved points on a circle, and it can be minor (less than half the circle) or major (more than half the circle).* 04:37 📐 *Minor arcs are shorter than half the circle, while major arcs are longer. Symbolically, minor arc AB is represented as \( \stackrel{\frown}{AB} \).* 05:19 🔄 *The length of an arc (minor by default) can be calculated using the formula \( \frac{\text{Angle}}{360} \times 2 \pi r \).* 07:13 📐 *To find the length of an arc, the angle is the central angle formed by the two radii (AP and BP) of the arc. Use the formula \( \frac{\text{Angle}}{360} \times 2 \pi r \).* 09:22 🔄 *The formula to calculate the length of a minor arc (e.g., AB) is \( \frac{\text{Angle}}{360} \times 2 \pi r \), where the angle is the central angle (alfa).* Made with HARPA AI

Diket : PK = e = 12 cm Sudut KPL = 135° Dit : panjang busur KL? Jawab: Panjang KL = 135°/360°×2π12 = 3/8 × 2π12 = 3/4π × 12 = 3π × 3 = 9π cm

kak mau nanya bagaimacara kita mencari sudut 120 itu kak dari hasil panjang busur 44 cm itu kak , kalau misalnya sudutnya tidak di ketahui kak, dan terus kita mau mencari sudut tersebut di dlaam lingkaran , bagaimana ya kak, terimakasih
@bsmathchannel4483
@bsmathchannel4483 Жыл бұрын
Tetap pakai rumus panjang busur kak, dimana nnti yng dicari adalah alfa (a) sudut pusatnya kak. jadinya 44 = a/360 x 2πr atau a = (44x360)/2πr

Iyya kak bisa, itu kalau di bulatkan jadi nya juga 44. Tapi untuk penggunaan nilai phi menyesuaikan nilai jari-jarinya kak, karena disoal jari-jarinya 21 maka kita pakai phi 22/7.
