ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ᴀ ᴄɪʀᴄʟᴇ ɪs = $2\pi r$

$\implies$ғʀᴏᴍ ǫᴜᴇsᴛɪᴏɴ,

$\implies$ᴘᴇʀɪᴍᴇᴛᴇʀ ᴏғ ᴀ ᴄɪʀᴄʟᴇ ɪs = 35.2ᴄᴍ

$2\pi r = 35.2 \\ r = 35.2 \times \frac{1}{2\pi} \\ r = 35.2 \times \frac{7}{22} \times \frac{1}{2} \\ r = \frac{246.2}{44} \\ r = 5.59$

ғᴏʀ ᴛʜᴇ ᴀʀᴇᴀ ᴏғ ᴄɪʀᴄʟᴇ = $\pi {r}^{2}$

$= 3.14 \times {5.59}^{2} \\ = 3.14 \times 31.24 \\ = 98.11c {m}^{2}$
