haii kak bantu dong pliss butuh banget noo ngasal yess wajib pake caraa

nxyaptrf

Penjelasan dengan langkah-langkah:

d² = p² - (r1+r2)²

15² = 25² - (12 + r2)²

225 = 625 - (12+r2)²

(12+r2)² = 625 - 225

(12+r2)² = 400

12 + r2 = √400

12 + r2 = 20

r2 = 20 - 12

r2 = 8 cm (c)

___________________________________________

r2 = (√P² - D²) - r1

r2 = (√25² - 15²) - 12

r2 = (√625 - 225) - 12

r2 = (√400) - 12

r2 = (√20²) - 12

r2 = 20 - 12

r2 = 8 cm
