Question

the radius of a circle is 14cm. find its perimeter​

Answer 1

Answer:

Given :-

• A circle whose radius is 14 cm.

To Find :-

• What is the perimeter of a circle.

Formula Used :-

[tex}\clubsuit[/tex] Perimeter of Circle Formula :

$\bigstar \: \: \sf\boxed{\bold{Perimeter_{(Circle)} =\: 2{\pi}r}}\: \: \: \bigstar$

where,

• π = Pie or 22/7
• r = Radius

Solution :-

Given :

• Radius = 14 cm

According to the question by using the formula we get,

$\implies \bf Perimeter_{(Circle)} =\: 2{\pi}r$

$\implies \sf Perimeter_{(Circle)} =\: 2 \times \dfrac{22}{7} \times 14$

$\implies \sf Perimeter_{(Circle)} =\: \dfrac{2 \times 22}{7} \times 14$

$\implies \sf Perimeter_{(Circle)} =\: \dfrac{44}{7} \times 14$

$\implies \sf Perimeter_{(Circle)} =\: \dfrac{44 \times 14}{7}$

$\implies \sf Perimeter_{(Circle)} =\: \dfrac{616}{7}$

$\implies \sf\bold{Perimeter_{(Circle)} =\: 88\: cm}$

$\sf\bold{\underline{\therefore\: The\: perimeter\: of\: a\: circle\: is\: 88\: cm\: .}}$

Answer 2

perimeter of circle =2πr

radius = 14 CM

2*22/7*14=88m

hence the perimeter of circle is 88 m
