ꜰᴏʟʟᴏᴡ ᴛʜᴇ ᴀʙᴏᴠᴇ ꜱᴛᴇᴘꜱ !!

Step-by-step explanation:

ᴡʜᴇɴ ᴀ ʀɪɢʜᴛ ᴛʀɪᴀɴɢʟᴇ ᴡɪᴛʜ ꜱɪᴅᴇꜱ 6 ᴄᴍ, 8 ᴄᴍ ᴀɴᴅ 10 ᴄᴍ ɪꜱ ʀᴇᴠᴏʟᴠᴇᴅ ᴀʙᴏᴜᴛ ᴛʜᴇ ꜱɪᴅᴇ 8 ᴄᴍ, ᴛʜᴇɴ ꜱᴏʟɪᴅ ꜰᴏʀᴍᴇᴅ ɪꜱ ᴀ ᴄᴏɴᴇ ᴡʜᴏꜱᴇ ʜᴇɪɢʜᴛ ᴏꜰ ᴀ ᴄᴏɴᴇ, ʜ = 8 ᴄᴍ ᴀɴᴅ ʀᴀᴅɪᴜꜱ ᴏꜰ ᴀ ᴄᴏɴᴇ, ʀ = 6 ᴄᴍ.

ꜱʟᴀɴᴛ ʜᴇɪɢʜᴛ ᴏꜰ ᴀ ᴄᴏɴᴇ, ʟ = 10 ᴄᴍ

ᴠᴏʟᴜᴍᴇ ᴏꜰ ᴀ ᴄᴏɴᴇ = 1/3 πʀ2ʜ = (1/3) x (22/7) x 6 x 6 x 8

⇒ 6336/21 = 301.7 ᴄᴍ3

ᴀɴᴅ ᴄᴜʀᴠᴇᴅ ꜱᴜʀꜰᴀᴄᴇ ᴏꜰ ᴛʜᴇ ᴀʀᴇᴀ ᴏꜰ ᴄᴏɴᴇ = πʀʟ

⇒ (22/7) x 6 x 10 = 1320/7 = 188.5 ᴄᴍ2

ʜᴇɴᴄᴇ, ᴛʜᴇ ᴠᴏʟᴜᴍᴇ ᴀɴᴅ ꜱᴜʀꜰᴀᴄᴇ ᴀʀᴇᴀ ᴏꜰ ᴀ ᴄᴏɴᴇ ᴀʀᴇ 301.7 ᴄᴍ3 ᴀɴᴅ 188.5 ᴄᴍ2, ʀᴇꜱᴘᴇᴄᴛɪᴠᴇʟʏ.
