Dari gambar disamping, OP = 26, AB = 24 dan BP = 4 cm. Hitunglah panjang jari - jari OA.

Diketahui
↪OP = 26 cm
↪AB = 24 cm
↪BP = 4 cm

Ditanya OA

jawaban ;
==========

(OA - BP)² = OP² - AB²

(OA - 4)² = 26² - 24²

(OA - 4)² = 676 - 576

(OA - 4)² = 100

(OA - 4) = √100

OA - 4 = 10

OA = 10 + 4

OA = 14 cm ✔


Semoga membantu ✔
