Question

A circular wire with radius 14 cm is cut and made straight then what will be its length?​

Answer 1

Length of wire=Circumference

• Radius=r=14cm

We know

$\boxed{\large{\sf Circumference=2πr}}$

$\\ \Large\sf\longmapsto Circumference=2\times \dfrac{22}{7}\times 14$

$\\ \Large\sf\longmapsto Circumference=2\times 22\times 2$

$\\ \Large\sf\longmapsto Circumference=44\times 2$

$\\ \Large\sf\longmapsto Circumference=88cm$

Answer 2

Answer:

87.96=88

$c = 2r\pi = 2 \times 14 \times \pi= 87.96$
