Mencari R dan r
[tex]\begin{array}{c | c}\begin{aligned} R &= K/2π \\&= 20π/2π \\&= 10~cm \end{aligned} & \begin{aligned} r &= k/2π \\&= 6π/2π \\&= 3~cm \end{aligned} \end{array}[/tex]
Mencari Panjang AB
Dengan menerapkan Teorema Pythagoras, panjang tali busur dapat ditentukan dengan cara sebagai berikut:
[tex]\begin{aligned} AB &= 2 × \sqrt{R² - r²} \\&= 2 × \sqrt{10² - 3²} \\&= 2 × \sqrt{100 - 9} \\&= 2 × \sqrt{91} \\&= \boxed{\bold{\underline{2\sqrt{91} \: cm}}} \end{aligned}[/tex]

Panjang Garis AB :
= 2 × √R² - r²
= 2 × √(20π ÷ 2π)² - (6π ÷ 2π)²
= 2 × √(20 ÷ 2)² - (6 ÷ 2)²
= 2 × √10² - 3²
= 2 × √(10 × 10) - (3 × 3)
= 2 × √100 - 9
= 2 × √91
= 2√91 CM
