ସେ.ମି. ହେଲେ ଏହି ବୃତ୍ତର ବ୍ୟାସ କେତେ
ସେ.ମି. ହେବ? *​

Answer 1

Step-by-step explanation:

ମନେକର......

${ redious=x      }$

$\implies{   2\pi R    =88cm    }$

$\implies{  2\pi ×x=88cm.       }$

$\boxed{\blue{   \pi=\frac{22}{7}       } }$

$\implies{ 2×\frac{22}{7}×x=88cm          }$

$\implies{   \frac{44}{7}×x=88cm.     }$

$\implies{   x=88×\frac{7}{44}        }$

$\implies{  x=2×7         }$

$\implies{   x=14        }$

$\implies{r=14cm           }$

$\implies{  ବ୍ୟାସ=2×r         }$

$\implies{   ବ୍ୟାସ=2×14      }$

$\implies\boxed{\red{   ବ୍ୟାସ=28cm       }}$
