A triangular wire whose perimeter is 28.26cm is bent into a crcle.find the duameter of the triangle circle( take π= 3.14)

$\huge \sf {\orange {\underline {\pink{\underline{Answer :-}}}}}$

Here,

Perimeter of a triangle=circumference of a circle.

$\sf\leadsto{28.26=2×3.14×r}$

$\sf\leadsto{28.26=6.28r}$

$\leadsto\sf\dfrac{28.26}{6.28}{=r}$

$\sf\leadsto{4.5=r}$

$\sf\leadsto{diameter=2r(given)}$

$\sf\leadsto{d=2×4.5}$

$\sf\leadsto{d=9cm}$
