Question

the diameter of a circle is 14 cm. find its circumference

Answer 1

$diameter \: of \: circle = 14 \: \\ radius = 14 \div 2 = 7 \\ circumference \: of \: circle \: = 2\pi \times 7 = 44cm$

Answer 2

Answer:

$Circumference\: of\: the \\\:circle = 44\:cm$

Step-by-step explanation:

$The\: diameter \:of\: a \:circle\\ (d)=14\: cm\: (given)$

/* we know that,

$\boxed {Circumference\: of \:a \:circle (C)\\=\pi d}$*/

$Here,\\C=\frac{22}{7}\times 14\:cm$

After cancellation, we get

$C = 22\times 2$

$C = 44\:cm$

Therefore,

$Circumference\: of\: the \\\:circle = 44\:cm$
