`\rm{A = \: \pi {r}^(2) (Area \: of \: a \: circle)}`

`\rule{70mm}{2.2pt}`

`\large \purple{\sf{Given→}} \\ \\`

`\rm{Diameter (d)→26 } \\ \rm{\: we \: know \: that \: radius \: is \: half \: of \: diameter} \\ \rm{r = (26)/(2) } \\ \\ \rm{r = \cancel (26)/(2) } \\ \\ \rm{r = 13}`

`\rule{70mm}{2.2pt}`

`\\\large \purple{\sf{Let's solve→}} \\`

`\rm{A = \pi * {(13)}^(2) } \\ \\ \rm{A = \pi *126} \\ \\ \rm{A = (22)/(7) * 126 } \\ \\ \rm{A = \frac {22} { \cancel{7} } * \cancel{126}} \\ \\ \rm{A =22 * 18} \\ \\ \rm{A = 396}`
