Penjelasan dengan langkah-langkah:
l² = p² - (r1-r2)²
24² = 25² - (r1 - 5)²
576 = 625 - (r1 - 5)²
(r1-5)² = 625 - 576
(r1-5)² = 49
r1 - 5 = √49
r1 - 5 = 7
r1 = 7 + 5
r1 = 12 cm (b)
___________________________________________
r1 = (√P² - I²) + r2
r1 = (√25² - 24²) + 5
r1 = (√625 - 576) + 5
r1 = (√49) + 5
r1 = (√7²) + 5
r1 = 12 cm
