Question

Find the circumference of a circle whose diameter is 14 cm. Take π = 22/7​

Answer 1

$diameter \: = 14 \: cm \\ r = \frac{d}{2} \\ r = \frac{14}{2} \\ r = 7 \: \: cm \\ the \: circumference \: of \: a \: circle \: = 2\pi \: r \\ = 2 \times \frac{22}{7} \times 7 \\ = 2 \times 22 \\ = 44 \: \: \: cm \: \: (answer) \\ \\ \huge \huge\huge\mathcal{\fcolorbox{lime}{black}{\pink{From:-ItzSuperBranded03}}}$

Answer 2

Hello mate..

$\huge ✼\mathfrak \pink{solution : }✼$

GIVEN:

Diameter of the circle = 14cm.

$\bold{ \implies \: r = \frac{d}{2} } \\ \small \bold{r = 7cm}$

$\bold {\pi = \frac{22}{7} }$

TO FIND:

Circumference of the circle.

$\bold \green{circumference \: of \: circle = 2\pi \: r}$

$\bold{ \implies \: 2 \times \frac{22}{7} \times 7} \\ \bold{ \implies \: 2 \times 22} \\ \bold{ \implies \: 44cm}$

∴ Circumference of the circle of diameter 14cm = 44cm.
