Find the circumfrence of the circle

Aishwarya · Answer

Let the radius of the circle be r cm Given, Circumference of a circle = Diameter of the circle + 16 8 cm ∴ 2πr = 2r + 16 8 cm $n n \Rightarrow n 2 n â¢ n n n \times n â¢ n n n n \frac{n}{n 22 n} n â¢ n n \times n â¢ n n n n r n - n 2 n r n = n 16 8 n â¢ n n n cm n n \Rightarrow n \frac{n}{n 44 n r n â¢ n n n - n n n 14 n r n} n = n 16 8 n â¢ n n cm n n \Rightarrow n \frac{n}{n 30 n r n} n = n 16 8 n â¢ n n cm n n \Rightarrow n r n â¢ n = n n \frac{n}{n 16 8 n â¢ n n \times n â¢ n n n n 7 n} n cm= 3 92 cm n n$ Circumference of the circle = $n n 2 n π n r n = n 2 n â¢ n n n \times n â¢ n \frac{n}{n 22 n} n \times n â¢ n n 3 92 n â¢ n cm = 24 64 n cm n n$
