Question

The circumference of circles

Answer 1

`\qquad\qquad\huge\underline{{\sf Answer}}♨`

Let's find the circumference of given circle ~

Circumference :

`\qquad \tt  \dashrightarrow \: \pi{d}^{}`

where, d = diameter

Now, let's calculate it ~

`\qquad \tt  \dashrightarrow \: c = 4×\pi{}^{}`

`\qquad \tt  \dashrightarrow \: c = 4\pi\: \: in`

That's the answer I terms of π, but we can also plug in the approximate value of pi as 3.14

`\qquad \tt  \dashrightarrow \: c = 4 * 3.14{}^{}  \\\qquad \tt  \dashrightarrow \: c = 12.56\: \: in\\\qquad\tt \dashrightarrow \: c \approx 12.6\: \: in`
